ok, the aquarium club i belong to is having a contest to those who can house an angelfish. Well i have a few tanks that could. I put the little guy in with my female guppies and hoplos in a tall 40g. How many other angles should i put in there? I know that they prefer groups. I want him to be happy. He is slightly larger than a quarter (not including the fins). I got another one today slightly smaller, no aggression so far.
