Hello, I have a juvenile RTBS in a 40b right now, and I was wondering if it would be better off in a 40b ALONE or a 55g ALONE? I am not really a fan of the 55g, but I have read it is the minimum required tank for a RTBS. I guess they can use the extra foot to swim but I would think the lack of depth can't be good either. Also, the 55g is about 4-5" higher, so that has to be a plus. I can go either way, just want whats best for the fish. Thanks!
