I have Yellowtail Damselfish in my tank for cycling just planning ahead i dont know what to do with the fish I'm planning for clowns,tang, pretty much Nemo and his friends but the Damselfish wont be able to hang with them or is a yellowtail damselfish the least aggersive? Besides that the germans dont take fish back once you buy them so the fish is SOL unless i figure a way so he could be with the other fish.
