whoa that's huge! lol! I dunno the size of the tank I;m getting all i know is it has a filter. Once I caught mino's from the lake and kept them and they didn't last over 3 hours!I'm not sure if they have a short lifespan or they are just hard to keep alive in captivity, I actually had him in with my betta but he didn't even care he just looked at him and swan around him a few times and did nothing else....the mino definitly wasn't attacked he was in perfect condition.
