View Full Version : Max Stocking

I take care of a 30 gallon at my Local Pizza store. We plan to setup a 110G tank in it's place. 2 Motoro sting rays will be put inside. For a 110g that is max stock correct?

Depends on the foot print of the tank..

Add another 0 to the end there and you could have rays. In a 110 gallon though I wouldn't try it. Motoro Rays can get 20+ inches in aquariums, probably twice that size though, I can't really remember, but at least 20". That itself, seeing as most 100-125 tanks are 6 foot long and 18 deep, really not big enough for a ray. I have seen a 110 at the LFS with the same footprint as a 75 only alot taller and that would be way too small.

All in all, I'd look at something else for the tank. When spending 100 or more on a fish you don't want to stunt them.

Their are much smaller rays out their. Some only get 8 inches and if the tank is wide enough would work.

The 110 is 4 Feet long and 2 1/2 feet tall.

When they say footprint, they mean length and width, not height. That's what's important to rays, not to mention most aquarium fish.

There are freshwater stingrays in the amazon! I have seen them at my LFS. They stay relatively small.

Yes, all the freshwater rays are from Amazonia, but no they don't stay small. The males (which are smaller) of the smallest species hit about 12" diameter, plus about 1.5x that of tail. Some species can be over 3' in diameter.

Will you be selling them or is this a permanent stock for a display tank? If they will be for sale then it will be fine since you won't be getting full grown adults. If this is for display only then that tank is far from large enough for motoros. Custom tanks with ray-friendly dimensions are ideal (like 6 feet long, 4 feet wide, and 12" tall).
