Well I might get shot but I was at the
LFS today and there was a couple of very cool Cortez rays or at least that is what the dealer called him the larger was maybe 7-8 inches round he said that would be about as big as he got mine is maybe half that I wanted to get some differnt things for my tank 150 galons and well rats are assome there is little info about them so I had to trust the
LFS I have delt with him a couple of times and always been pretty honest said they were pretty hardy. of course snails and crabs may be at risk but they have been eating shark meat pretty reguler and said he hasn't
been bothering other stuff even snails or crabs in the tank. so can anybody probide more info
