Hello,
I am planning on upgrading to a bigger tank (the 12gal. nano quickly became to small over the last year and a half). I'm thinking of taking my old 40 breeder back out or maybe go and buy a 55. The one fish I always wanted in my tank is the mandarin fish. my only concern is that if I go with my old 40 or get a 55, it will be too small for one. will either of these sizes be enough room? or should I think about going a little bigger?
