I have a 55g tank w liverock. Currently I have a Niger trigger, Lunare wrasse, and 4 damsels. The Niger and wrasse have been in the tank for 3 days, the damsels a week prior. I don't really care about the damsels staying in the tank. I was think of adding a couple of clowns, tomato or maroon, or a yellow tang. I would stop adding fish at that point. Which is better? Should I add them soon before terr is established? The tank is aprox 7 months. Thanks for any reply.
