Is it ok to have 3 perc clowns in a 20 gallon with 1 GBTA? Im wondering if the perc that isnt apart of the bonded pair will fight with the bonded pair, or will they get along and how can i get around getting rid of the 3rd clown. I want whats best for all of them and i want them to live along time and not be stressed out. I also have a 4th but its in a med tank because he has ick im sure.
