I setup a new Jellyfish tank.

[Justin_James]

I just finnished setting up a 25 gallon jellyfish tank. I used a tall 25 gallon tank, a filstar xp3 canister filter and a tank divider.

I cut the tank divider and made a 3 sided box that I siliconed to the bottom back corner of the tank and then I cut a hole in the top that I stuck the intake of the filter inside to ensure that no jellyfish get sucked into it. I then used a spraybar for the return aimed at the back pane of glass and slightly downward to make a rollover effect in the tank so that the jellies can remain moving in the water colum. There is no substrate and no live rock, just a bare glass tank. All the bio media is in the filter cycleing as of right now. I will be getting my jellies from the local beach once we get a fine day to go collecting. The species I will be keeping are called "Moon Jellies".

There is a 50/50 % chance this will work. If it does i'll be sure to let everyone know the cheep way to keep jellies. :thumbsup:

[Justin_James]

Here are some pictures of my setup. When the filter is running the sponge you see in the photos is suspended in the water and keeps moving just like the jellyfish should. I added anouther section to my intake box since there was a dead spot in the corner. All is well now.

[oceanscurve]

:drool: wow that is so cool. Ive been thinking about new tank and that very well could be what I do.

Thanks,

Tom

[DarthLungFish]

Wow, Good Luck! I would like to know how it works out for you!! :grinyes:

[Justin_James]

Thanks people. I'll be sure to post my experiences once the tank is cycled and I have some jellyfish.

[thamunsta]

are the jellys dangerous ? and what other types of small saltwater fish/inverts do u find up that way, ive been thinking about taking a trip to the nova scotia/newfoundland area to go snorkling and collect sw species for my 20g tank.

by the way nice idea! cant wait to see pics

[Justin_James]

No, the Jellyfish im getting are not dangerous, They are called moon jellies and are native to this area. Well to tell you the truth there isn't much in our waters. I've been told that there is stuff like moray eels, groupers, crabs, snails, starfish, and outher more unattractive fish but not much to interest a reefer. But you might prove me wrong and have a great collection day. Where are you from?

[thamunsta]

im from ontario (near toronto) i remember seeing a red starfish in the ocean in newfoundland on some rocks as a child. i really want to go back and see what i can catch.

[davo]

i thought jellies didnt do well in square/rectangular tanks?

[Justin_James]

Well it's difficult to attain the roll effect in a square tank but I have achieved it quite nicely. There are jellyfish tanks made from normal tanks that have slops made out of acrylic that are siliconed down into the front and back corners where the front and back meet the bottom pane but with my spraybar I didn't need to do that. If this doesn't work out for me then I will try some outher stuff but I actually got to talk to the guy that owns "MIDWATER SYSTEMS" and had a great talk with him over the phone and he says that my system will probably work. He said to test with a piece of papper towl and see where it goes so that I will know exactly how the jellyfish will move so I did. It worked like a charm and the papper towle stayed in the center of the tank with a gently rolling effect.

[davo]

interesting... i cant wait to here how this all goes!

[messiner]

im thinkin you are gonna get a big blob in the corner. moon jellies get big you know? like a good foot across. upsiedown jellies can be placed in rectangle tanks but other than this ive yet to see.

[Justin_James]

I will be collecting my moon jellies from the ocean so I will be able to choose what sizes I like, They live for few years and it take a couple years before they reach any where near the one foot mark, Also when they do get too big for my system I can just return them to the ocean and get some new ones. The upside down jelly requires more work than the moon jelly since they are much more sensitive and need very strong light to survive where moon jellies don't need any light.

[Bassman89]

what do jellyfish eat anyways??

[Justin_James]

Well the diet of a jellyfish ranges from species to species but the particular species I will be keeping (moon jellies) eat plankton and do very well on newly hatched baby brine shrimp. Some jellies are photosythic and need very strong light to survive since they make their food inside their bodies.

P.S. Did you know that the Portiguees man of war isn't a jellyfish? It's actually made up of multiple animals and not just one.

[messiner]

yeah i forgot about how the upsidedown jellies harvest algae and all. gl with the moon jellies. we used to feed cyclopsies to the jelly fish at mote.

[dr_sudz]

I have never seen jellys kept before! I want to see a pic of them in the tank when you got them all going.

[Justin_James]

I'll be sure to post pics once it's running. :)

[sharkguy]

if anyone is intrested in florida jellys dunno any names cause i dunno anyhtign about jellys but i can collect tehm if theyd survive shipping to whereever?

[Justin_James]

Thats a very kind offer shark guy but I have found out that the moon jellies are the easiest to care for so I better start with them first but thanks for the offer just the same.

[swingsetredemption]

Your set up for this is quite unique. It seems like it will work but you never know untill you try i guess. If you do end up keeping moon jellies and feed them brine, make SURE you keep up on your cleaning/ syphoning. If you leave un eating brine in the tank for to long they will cling to the sides and become hydoroits, (sp), they can/ will dismember you jellies. If I feel motivated I will bring a camera with me to my internship and take a few pics of their setups on their jelly tanks. Have fun with the jellies though.

not to derail but another iowa member nice where from in iowa

[philliptobin]

My upside-down Jellies are getting the same care as my corals, and they are growing. I would have to say that they are just as easy to care for as polyp corals. I tried posting pictures but they were to big, I will try to reduce the size and attempt to post again. Good luck with the Moon Jellies.

[philliptobin]

my Jellies

[Justin_James]

Thanks for the photos and the info.

[DeLgAdO]

i thought jellies didnt do well in square/rectangular tanks?

they dont

its not gunna work

i guarentee it

they need cylinder tanks with slight circulation gonig in one direction, they will smash themsleves against the 90 degree tank wall and get stuck in the corner.

that spray bar is gunna mess them up when they get close enough

aeration of any kind will tear them apart, they are very fragile invertabrates.

bubbles will make holes in them.

also they need a chiller, they dont tolerate cool or warm water.

[Justin_James]

Thanks for the polite boost of confidence!:thumbsup: Will just have to wait and see what happens.

Note true, if you set it up right it can be done. I have seen it many times before. I'm not to sure how well this set up will work, but you can keep moon jellies in a rectangular tank. But you are right about the chiller, moon jellies need the temp. to be at about 54 degrees.
-justin

[Justin_James]

Well as of right now there are two moon jellies floating around in my tank. So delgado, how well do you stand by your guarentee???????. I collected them and a hole crap load of snails for my shark tank as well.

So yes you can keep jellyfish in a tank like I designed. They are also eating the baby brine shrimp I put in for them as well.

Stay tuned for some photos within the next week or so since I have to remember to pick up some batteries for my camera.

Now i'm going to experiement with the lighting to see how cool I can make it look. :woot:

[lil_blue]

how are you gonna feed them often enough?

if i remember right, dont they need food 2-3 times a day?

[dr_sudz]

I take my hat off to you! This is what this hobby is all about! Trying new things, sharing and making it all around better and opening new ideas to the floor. Don't know for sure if anything will work unless you try, mistakes are made and some become million dollar ideas.

[Justin_James]

if i remember right, dont they need food 2-3 times a day?

I will do the same thing I do with my seahorses. I just hatch enough brine so that there is a clowd of it in the tank and it will last all day and all night right up until the next batch is ready. That way there is a constant supply of food at all times.

[Motoraygirl19]

well, that's gonna be interesting to see when you get some pics up!! Moon jellies are common, but they're neat anyways. Good luck! I hope everything goes well!

How's it working so far? It sounds awesome!

[bermuda]

Now i'm going to experiement with the lighting to see how cool I can make it look. :woot:

how about a LED light system on the bottom? you can program LEDs to do that cool color change trick that people have to put under crystals and stuff. i bet that would be AWESOME with moon jellies. you can layer a super thin layer of white sand, clear fake rocks, or just scuff up the bottom of the tank to help disperse the LED bulbs themselves... is there a reason this is bad? i just thought it would be neat... :D

its better if no decreations are in the tank. but the led light may be cool

[Justin_James]

Everything is doing fine so far but the jellyfish have large cuts in them and the cuts are spreading so I don't think they will survive. They were like that when I got them. I would have gotten healthier ones but they were the only two around so I took them anyways.

I like the LED idea and I could put them above the tank aiming down so that they wont effect the jellies. I'll have to look into it.

[davo]

do you have any pics?

[Justin_James]

Not at the moment but I will hopefully sometime this weekend.

[DeLgAdO]

any updates?

[Gr8KarmaSF]

go for it!!!

and if it doesnt work this time then try try try try try AGAIN!!!

dont let people tell you it wont work....

[Newt]

So how's it working out with the jellyfish?

Do you have a chiller on the tank?

Great to see someone experimenting a little!

[catfish]

that is sweet ive been waiting for a while to see someone do a jellyfish tank

[Justin_James]

The jellyfish tank was a success after a little tweeking with water currents. The two jellies with the toren bodies did not survive since their tares keept spreading. I went and got some more and keept them for a while but to tell you the truth they were kinda boaring. I thought I would really like it but it wasn't busy enough for me. I since have given the jellies back to the ocean and turned the tank into a FOWLR for my wife.

[sprayin70]

Here are some good links to help your new project. These links are about keeping jellies and Jelly aquariums.

Enjoy.

do you have any idea how flawed that statement is? :eek:

[Gr8KarmaSF]

how so?

dang mike, im just trying to encourage the guy...

:irked:

[DeLgAdO]

how so?

dang mike, im just trying to encourage the guy...

:irked:

hehe see??? its the misinterpertation of tone!!! :nilly:

the idea environment for jellies would be a cylinder tank.

ive tried keeping these bastards in square/rectangular tanks

its usless, eventually then run into the 90 degree panels so much they get destroyed or torn up badly, regardless of how the current is flowed

to keep trying to have them in a rectangular tank would be pretty pointless and a waste of jellie life.

[Justin_James]

go for it!!!

and if it doesnt work this time then try try try try try AGAIN!!!

What you said was an encouragement and thats how I took it. Thanks.

I don't know what your problem is with me keeping jellies DeLgado but it's starting to irritate me.:chillpill: :chillpill: :chillpill:
:irked: :irked: :irked: :irked: :irked: :irked: :irked: :irked:

[Justin_James]

I had no problems keeping healthy caught jellies in the tank I constructed. "NO" jellies were caught in any 90 degree corners because my current keept them away from them. If you don't believe me than thats not my problem. I don't come here to get harrassed and argue with people who are ticked off because they couldn't keep jellies too.

[Gr8KarmaSF]

if you rig the current enuf and just right with powerheads i think that it could be done!

it might take alot of experiementing and wasted jelly thou...

you have my attention

how did you rig this current to keep them from banging in?

how long did you have em before you returned them to the ocean?

and i did maintain jellie successfully too btw ;)

ever been stung? :eek:

[Gr8KarmaSF]

i did get stung once while surfing in hawaii.....

[DeLgAdO]

i did get stung once while surfing in hawaii.....

its last awhile doesnt it? :D

vinegar didnt even help

i heard if you piss on it it goes away

im not willling to try it though :naughty:

[Justin_James]

Ok DeLgAdo, as long as your not trying to point me out to be a fool i'll discuss this issue with you. I'm sorry I had to snap back but I strongly felt you were lashing out at me in past posts.

[Gr8KarmaSF]

its last awhile doesnt it? :D

i heard if you piss on it it goes away

im not willling to try it though :naughty:

hurt alittle but with some scaring.

let me know if you ever get stung...ill piss on you :D

I'll save everyone because my wife tells me i'm full of piss and vinager. :ROFL:

How long did you keep the two jellies that you later released and were they as healthy as you found them.

[DeLgAdO]

I'll save everyone because my wife tells me i'm full of piss and vinager. :ROFL:

LOL!!!!:ROFL: :ROFL: :ROFL:

[Justin_James]

Well the first jellies that I caught had tares in their bodies and the tares spread and they finally died but the second time I was lucky enough to have more to pic from and I choose very healthy ones. I had them for about 1 month or 5 weeks and I soon became board with them. When I dumped them back into the ocean. They were pumping along just as well as the day I caught them.

[H20Boy]

It’s one thing to say my napkin tumbled around it’s quit another to sustain life for a month.
I would say that qualifies as a success, I was just curious if they got infected or were showing sings of stress that is often the result of them bumping into each other or the walls of the tank.
Congratulations

[fishyboi]

My friend does jelly fish, and he said they do best in a circle tank and the circulation has to be rite. He spent a lot of money in his tank

[Scuba Kid]

You got rid of em before you posted pics????:(

[Justin_James]

Sorry, if my digital camera was working I would have posted lots. I have friends hitting me up for pics of my sharks all the time and they gave up on me. I gotta stop spending money on fish and invest in a new camera.

There were no signs of stress that I could tell. With jellies it's hard to tell if they are happy. The main thing I went by was how often them pumped per minute. It always stayed at a steady cycle between 30-35 pumps per minute right up till the day I tossed em back.

[Morgs202]

Nice set up! Definitly let us know how it works out

[DeLgAdO]

Nice set up! Definitly let us know how it works out

gotta read the whole thread dude ;)

[Max]

How long did you keep them? Just curious I love jellies,hydriods etc. Do you think that they would have made it long term in that style of set up. I understand that you probably faced your powerheads into the corners but, how did you manage to achieve an equal flow ratio and avoid the jellies congragating in one area of the tank? How warm do the oceans off the Canadian east cost get in the summer?
sorry ,I'm curious

[noreaster]

No, the Jellyfish im getting are not dangerous, They are called moon jellies and are native to this area. Well to tell you the truth there isn't much in our waters. ?

Arg ! I can't believe I just heard a maritimer say something like that !!! :irked:

There are lots of good fish in our waters you bluenoser . ;)


:D

[Justin_James]

Hahaha. Oh, no. A funny newbrunswicker. :grinno:

I've heard that if you go diving way out there is a few neat things and fish to be seen. Close to shore there isn't much though. I don't dive so I can't catch crap.:popcorn:

What side you live on ? The atlantic I take it not they fundy side ?

[Justin_James]

I'm in Sackville. Just outside of Halifax about 15 minutes with no traffic.

[noreaster]

How warm do the oceans off the Canadian east cost get in the summer?
sorry ,I'm curious


The waters here at the mouth of the Bay of Fundy reach from 12 celcius in the open water up to a high of 21 22 c in some of the Smaller of more shallow bays. bays

And have seen some of the smaller bays water reach low temps of minus 0.1 c

[Jellyman]

How is your jellyfish tank working? Are the moons still alive?

[Mantis411]

that is true the bay is alot warmer then the atlantic, and i have heard of some decent diving there (i myself don't dive) but my oldest brother does and appairently there are some good islands to dive at (i think the best one is called deer island? but i could be wrong on that)



and ya more jelly pics and updates

Deer island!!! ahaha my childhood camping spot! home of the biggest whirlpool in the world ya know. ;)

Anyways the whole Bay of Fundy is fantastic for life, i used to keep a couple of natives off of the beach, i kept a sculpin, a wolf fish, a green crab/hermit crab colony, a red-gilled nudibranch :D, and a crap load of amphipods where always swimming around (they bred easily, and sustained a small barnacle colony). These weren't all in the same tank obviously but some shared. My point is that theres alot of interesting things in the Bay of fundy, just off of the beach...you could get into flounder, squid, sea ravin, etc

A bit more on topic, I loved the Jellyfish idea, a pity he didn't keep it going, nice idea though.

here's a pic of the nudibranch i kept...i just loved the thing so much :headbang2
