i know very little about rays but i am very interested. I have a 265g all glass that has a foot print of 8'x24''. Can this house any ray for life. If so which one. My local lfs has what they are calling tea cup's but i do not know enough to tell them apart just yet. Is there any thing that a prospecting new ray owner should now that may be different from other fish. -----------A little back ground--i have been keeping fish for 20yrs now and have done just about everything from cichlids to US natives to bichirs to a few payara species to puffers and many many small fish. I have also done some salt in my life but never a large show quality coral tank or anything. Any help would be fantastic,,,,thanks
