Miles said:Oh, BTW.. Teacup rays have much smaller mouths and will have a hard time eating the 'typical' ray foods that most books/websites inform to feed, such as Squid/Krill/etc..
Also, your Apollo sharks and other tankmates are probably stressing the ray out.. They are delicate fish and can't just be thrown into any 'community' tank, contrary to what your LFS says.. Could be another of other problems too such as substrate, bio-load, etc..
If I were you I would try to take it back to the LFS and get some sort of credit before it perishes.. Purchasing a stingray before doing the research always leads to bad results!
so I am taking your advice. there will be a substrate change on half of my 125 gal. tank to accomodate the ray and a bunch of fish are going to be brought to the fish store and a friend. the end result of this project will be:
125 gal. tank (fluval xp5 filter) planted tank with plenty of room for the ray to move.
