if they are ones I am thinking of they are the southern stingray and they are easy to acclimate to freshwater from saltwater. just make sure to keep the water hard. also they get huge.
The key to keeping atlantic rays (Dasyatis sabina) is to have an already established tank. Then, over-filter, over-filter, and over-filter some more. These rays can adapt to FW but, at a price. Their renal functions increase tenfold in FW. That means 10 times the urinary output AND the subsequent 10 times the normal absorption of water. So, water conditions must be pristine at ALL times (plus lots of big water changes). If your setup keeps this concept in mind (along with the tank having a large footprint), these are a nice ray species to maintain. Especially for ray fans in riverine ray-unfriendly states
They are around 6-8" and will go for $80 each plus shipping.
Oddball is right. They come into the Freshwater of the St. John's River to breed and then go back out to see. Correct me if I am wrong Oddball, but it would be better to keep them in Brackish water, instead of straight Fresh.
This supplier also has small Tiger Dats for $15 each.
I am taking pre-orders for my customers here and will do the same for Online customers.

Geeze, that Oddball is always right on the money!. The only time I had good luck keeping the rays was in a 125 with 3 403 fluvals on it. Very active ray, easy to feed, eat just about any meaty food. Might have to 1 along with my tiger scats
A large portion of the St John's River ray population spends their entire lives in freshwater. These rays do breed regularly in the fresh alkaline water. One of the obvious differences between the total FW rays and the rays that move from fresh to marine to fresh again is that the completely FW rays tend to reach smaller total adult size than the migrating rays. There are physiological differences in liver size, renal activity, and osmotic regulatory processes but, I probably don't need to bore folks with that lecture.
