Mini Marbles

  • We are currently upgrading MFK. thanks! -neo
Id also love to know what your largest midget is :D

Last I measured she was 11" across.

Here's a pic of her after importation....... http://www.monsterfishkeepers.com/forums/showthread.php?213870-FEMALE-MARBLE-MOTOROS

I have a male I acquired around the same time that showed up mature at about 7-8" and is now 9" maybe 10".

I have larger Marbles, and many other species of rays, I know this isn't the result of the way they're cared for.

IF you see the pics of the tank that only has 3 rays in it, the female that wasn't in the breeding video isn't a midget. She's less then 2 years old and has caught the midgets already in size.

Ok, well thanks for the help :D
I think i might have seen your breeding video :D

11 seems to be a very small ray, those midgets really keep there size down :D

Again thanks for the help.

Why are you so worried about the size of the ray if you getting a 8x4 a tank that size can hold lots of different rays

I know people who have kept bd pearl p14 henlei in a tank that size for well over 6 years with.no problem

The way you keep asking about the smallest ray it makes me wonder if you are actually getting a 8x4 as a lot of people on this forum would tell you it's big enough myself included

I guess i understand, why your doubting that im getting a tank that size.
I guess im not like other MFK's. I have in a long time wanted to make a large discus tank, and large ray would eat them.
When you say in well over 6 years your implying that id have to upgrade again some time, wich is something im most likely not gonna do.

Smaller always means more swimming space, then they can live more like "normal fish" if you understand what your saying :D

Ofcourse im gonna build the tankmates around the ray, so if the discus id dosnt seem to hold up when i do some more research into that.
Also if you have a smaller ray you can allow your self to decorate the tank more, with driftwood and such things, just gotta make sure theres no sharpe edges :D
 
I think you will find a very hi gh percentage of the advice being given to you is coming from people who don't have or never will have a 8x4

It all depends on what your end goal is but most tank mates are at risk from any ray

Yes small marbles maybe small but they are still motoro who are well known for killing tank mates

Big lumps of drift wood look great but they also trap loads of ray poo
People don't just keep tank open for more room but to keep on top of good water

It would be ok with me if every now and again a discus got eaten :) I could imagine the driftwood would have negative effect, i have also seen some people make a pretty nice, open roomed rocky aquarium. Basically there was one of those backtonature baggrounds on, and he had put these round rocks up against it, leaving lots of room for the rays. Well, right now its just being planned in the early stages. But a 15" stingray taking down a fullygrown Dsicus? Im sure its possible, but how it would do i just cant Picture in my head :) I have seen some people have Datnoids with there rays too, theyr pretty cool. What temperature is your ray tank at? I could imagine that being and issue with discus.
 
If a fish is smaller than the rays disk it is as risk and as far as I know you can't get 15" discus

Rays work much like a big suck like the type window or glass fitters use to move big sheets of glass
If the ray can cover the whole fish and keep that vacuum over the fish it has no way to escape
The ray tightens that vacuum killing the fish or sucking out its eyes

Datnoids seam to work as they have a razor sharpe dorsal fin the rays feel that and let go

Discus don't have that form of defence

Yeh ok. That sounds Extreme.

Not necessarily. They can be killers bro, alpha predators. Some love to hunt. If they can cloak over it, they can make a suction and pin it down suffocating them. While not physically squeezing them they can make a vacuum especially on a bare bottom and trap them, preventing them from breathing and using their sandpaper like teeth to shred scales and eyes.

With discus needing extremely pristine water, and rays being ammonia factories I think water quality may be an additional concern in addition to them becoming lunch meat.

There killing method sounds craazy, something id love to see :D

Im though it might work because rays and discus need pristine water.
I've heard that there agression, sometimes is diffrent from ray to ray, i might try discus, if it goes wrong its atleast not the rays that get heard :D

Well, i got a lot of time to plan, gotta move from my apartment, to house before i get rays :)
So i got a couple of months to a year to plan it all.
