Im not an expert but I think the people on this site will tell you that you need more width than 24inches for your ray. They like a lot of open space to sift through. If thats the word. But with out a lot of rock you "might" be able to pull it off while its small. The grouper will grow quick and big just to warn you though. But with all that said if you try it good luck!!!!! wish you the best.
