I originally got into fish keeping because I wanted a ray. Well after tons of research I decided to wait a bit now my LFS has 3, 5 inch Florida rays and I want to buy one. All 3 are males and are very active. My set up is a 120 gallon duel overflow sump system with a 400 gph canister filter too. (I like extra filtration ). My fish I have are peaceful I have 3 bichirs and 6 silver dollars. I have sand substrate and sword plants along the back side of my tank. Is my tank a good set up for this ray?
