Aquarium Advice Regular
I have a 20 gal tank with about 8lbs of LR and 5lbs of other rock with a sand substrate. I currently have only one 4 stripped damsel. I was curious as to how many more fish I can add. I would like two clowns or a clown and something else. The damsel was not aggressive, but he has had the tank to himself for sometime now. Should I be cautious?
