very hard to keep rays. i bought one when a few big shipments came in because its one of those dream fish but stingray keeper is spot on on the size, they will get big and bigger than your typical black or brown ray will. Right now I can give mine a good home but I will have to upgrade in a few years provided I can keep her that long.
Since I got her several months back she has been the most difficult ray to keep and still is. i've kept a variety of black and brown rays and even had success in breeding. Honestly if I could redo it I would have bought a nice p12,13, or 14. I spent 400 on my flower but have spent about 150 on meds (bacterial and parasite treatments) dedicated her own 225g tank, spent countless on live blackworms and even still she is not in 100% great shape and needs to put on weight, although I got her eating more finally.
Several members off of here bought one within the past few months and I know of a couple that havent made it and havent heard anything out of the rest of the ones that I know bought them.
