  • We are currently upgrading MFK. thanks! -neo

great looking fishes for sure...Cubans are quite impressive BUT...my gosh...tell me you're not cycling that tank with Cuban gars??? how long has that thing been up and running, and how recently was bacteria seeded into the tank? (feel free to reply back in your gar forum thread as well since i don't normally check the photo forum) --

think you must have missed out this thread and pic.

actually. i think that's what i'm doing. uh oh... the tank's been up for half a week. a third of the media in the 225(some ehiem pro media, biohome and bac house-not in the pic-) came from the 120 that the cuban gars were in. twice that amount, thou not as good(all the ceremic rings you see in the second compartment), came from the 75gal. all the media have been running on tanks for a couple of months. with 2 times(quality of media in mind) the media running on almost the same no of fishes, i don't see a problem. unless the bac die upon being moved into a new sump. which i am assuming and now praying as well they don't?
 
if there is one thing i have learned, it is NEVER cycle or establish a tank with cuban gars...they are far too sensitive. you aren't really cycling the tank, so that's a good point in your favor.
how much old media is in there and how much new media is in there? how many fishes are in there now, and what are their sizes? if the amount of established media (not NEW media) in the new tank is equal to the bioload of fishes you have in there then you may be ok, although there are still intangibles involved with starting up a new tank.
having that media in the new tank for only .5 weeks is not a good start. the tank should have been running with the old media and a MINIMUM bioload of fishes for at least a couple weeks. preferably just the bichirs. a drastic analogy to what is happening now is that of cycling a tank with paradise threadfins.

keep a close eye on the Cubans and their coloration. feed MINIMALLY. if i had known the plan ahead of time i would have definitely suggested moving the other gars in first or just using the bichirs. big tanks need a decent amount of time before they are established (not equivalent of cycling)...and this process can be very stressful on the fishes.

also keep in mind you don't want to change the water AS MUCH in a newly setup tank because it can interfere with the establishment of bacteria and balancing a lot of other issues (free-floating bacteria, floc, algae). in establishing your tank with very senstive species, however, you may end up needing to do more water changes, which will prolong the establishment period overall, and also cause stress on the fishes.

monitor your pH, ammo, nitrites very closely, and again, keep an eye on those Cubans. i know they will like the extra space, but it won't do them any good if chemical imbalances kill them. good luck and keep us posted--

There is no new media. all the media have been running on tanks with fish for a couple of months.

2xcuban gars, ~20inches
1xalligator gar, ~15inches
2xendlicheri, ~15inches


1/3 of the media(vol wise) was holding the 2 cubans and endlis in the 120 before this.

i can arrange for the endlicheris and gator gar to be moved if they're going to be a problem. i was looking through your gar den II thread and by looking at the dates of postings etc i was under the impression that you had added quite a lot of fishes pretty soon too after using old media. hence i decided to go ahead with the plan. was i mistaken?

i was originally planning on minimal feeding anyways. might go with 2xper week 10-25% changes?

thanks for taking the time, will do.

I was in agreance with Solomon...that filter/media looked way too clean to be cycled.. Hopefully everything works out though.

Edit: Awesome tank BTW. The fish should love it!
 
hey xander,

thanks for the detailed reply to my response. i don't have time to respond to everything at the moment, but you were correct in the original gar-den II stocking regime...it was a lot of fishes at a short time. also keep in mind that this was over 3 years ago and before we found out about the Cuban pH-fluctuation issue (it took some casualties to figure that out as well). hence i am trying to prevent you/your fishes from going through that as we have since learned quite a bit.

it took quite a while for that tank to become established, but luckily the other gars did just fine. this was also an issue because i had to move from one house to another, so it was actually a necessity in moving, not really convenience or just upgrading.

hopefully your fishes will do fine...i have no i doubt the gator and bichirs will be fine, it's the Cubans that should have an emergency home just in case...OR just monitor things closely. what's the volume on the new tank? luckily with a large volume toxins will be diluted, at the same time it's hard to modify the chemistry in a big tank.

keep us posted, monitor your fishes/tank closely, and it should work out--

thanks! the media is definately cycled. it's been running my tanks at perfect conditions for a while.

tank's ~225gals with about 15kg of crushed coral substrate. will add another 20kg when i'm free to go to the farm. thanks for the advise. will def keep a close eye on them!

That was just a snap judgement on my part. I always keep extra media packed in my filters for setting up new tanks. It makes the process much quicker.
 
beautiful gars xander
hey by chance how much does a cuban run?
how hard r they to get(i think i heard u say on 1 forum that they are endagered)?
