I was wondering if a 55 gallon is just right for 1 marble angelfish full size. I have currently a juvenile angel in a 20 gallon by itself. I was told that it would outgrow the system. Luckily my parents have a unused 55 gallon tank in their basement.
A fifty five gallon tank is good for a single angel,..or a pair. The twenty really is too small for a decent size adult angel. At the best, one angel in a twenty is okay, just a bit constricted, not too mean...I have to say that because I'm guilty of having pairs in 20's right now.
