so as you've heard i have four new discus in my 55 gallon aquarium. I was wondering if it would be okay to squeeze a fifth guy in there. My reasoning behind this is that the four i have school but there is one bully and it seems as if he might have zeroed in on the runt of the four because one of my discus isnt always with the main three and i think a fifth will equal out the pack a little bit so whats the thoughts on five?
