I was gifted my current habitants of my display tank. My cousin wanted to get out of the hobby so I took all he had 40 gallon breeder and habitants to my house. He asked me to take it since he knew I was building a 120 display set up. Got my 120 up and running and moved the habitants over. He had a few corals; frogspawn, zoa, and a polyp colony. The fish are Huma Trigger, Juvenile Koran angel, blue chromis, Fox face, and black ice clown. I have since added only 2 items; Kenya tree and coral beauty dwarf angel. I really want to add more corals, I am okay with soft or LPS/mixed. But concerned about a couple of the fish I have. If I want to add more corals, I assume I need to re-home the trigger and Koran? Any thoughts?
