I am sure I could find it somewhere but me and my BF are having a bit of a dispute over tank size. I say my tank is big enough for Leo's or any of the black rays and he says in no way is it. Most of you know me on here but for those that do not I have had rays now since 2006 I currently have 3 retic mature adults 4 CB retic pups and a mature true hystrix so really I think I know a little about rays he on the other hand came into this knowing nothing about rays and wants to argue with me over tank size so maybe I am wrong but I say my tank is big enough to house leo's or BD's he says no way. Tank dimensions are 96x48x25 with a 180 sump and a 30 gallon pup tank all ran on the same system. Just curious this is strictly just a debate at this point I have no interest in getting any new rays. Current water volume is around 680 gallons
