Hello all-
I was thinking 3 fish max for a 22gal. It's been up and running and stable for a while now, with the algae blooms finally receding. Currently, there we have a green chromis and a small sixline in the tank and we're looking for recommendations for a third and final addition of a tankmate that will form a peaceful trio. Any ideas?

thx! pete

Have you read lgreen's fish guide in the beginners forum? The main issue is the six line, which is semi-aggressive and best not kept with very peaceful fish.
