I would like to add a pair of clown fish to a 220 which already has a pair Clarkie. The large of the two is the devil it's self any advice on do this intro or if it's a good idea
I would strongly advise against this. I've seen tanks that are 500 gallons and 8 feet long where two pairs are introduced, and both have their own anemones on opposite sides of the tank, and still theyre constantly at it! Especially if you already have an established pair in the tank, I would say no.
