how many?

[foxhound]

i am just curious, for my furture plans, as to how many rays you can actually keep together. i know it depends on size of tank and species but i havent really found anything on aggresion between rays. so say for a tank with the dimensions of 72x36x 25tall how many could you fit in it with 2 being a pair of motoros.

thanks

I guess You'd have to think also about:

How stocked do you want the tank to be?

Can my Biofiltration handle it?

Can I afford it?

on the aggression side I have heard of ray aggression towards other rays and also to other fish. One of our staff redtailfool even had a Motoro kill his Fly River Turtle.

It really depends on the type of ray that you keep.

A female motoro can easily reach 18"+. A 6'x3' is really not big enough for one that size. However, you could keep a group of 3 - 5 adult histrix, scobina or magdalenae (retic).

Leopoldi, Tigers, Castexi & Schroederi all get very large as well.

thanks, yeah i would deifinately make sure i had enough biofiltration. i dont actually want to stock too many fish. my main plan is to have 2 motoros (hopefully a pair) and my aro. but it would be pretty neat if i could put a couple more different species of rays in it also.

later

colin, thanks. about what would the minimum width (front to back) need to be to keep an adult female that is 18"
i would have guessed 2 times her width but i dont really know.

thanks again.

I had 6 rays in an 8 by 3 by 1.5 foot tank. 4 were motoros and 2 were humerosas. Aggression got out of control and I just lost a 10" Humerosa that was badly bitten by another ray. I've been told that an 8x4x2 could max hold 4 adult motoros.....I don't think I would put more than two adults in your 6x3. The 6x3 would probably be fine for say 4 smaller motoros, but they grow fast and will soon be too much. I'm looking to get an 8x4x2 and will probably only keep 3 motoros in it....maybe 4.
