I have a 20 gallon tank and am thinking of getting a beta in there. As of now, I have 6 neon's, 3 catfish, 2 angle fish, 1 algae eating shark, and 2 gray fish that I am not sure what they are (they came with gold fish when I was starting my tank and was unable to get them out). I keep the temp of the water in the mid 70s and my ph level is around 7.
Do you all think a Beta would do well in this tank? Or would it try and fight the fish that are in there now? Or would the fish that are in there now nip at its colors? Any advise would be great, thanks.
