My 240 is not set-up yet ( probably one or 2 more weeks, I have almost everything already, I have all the fish and sharks already,,, a friend of mine works at a lfs, so they are all in a holding tank right know eating well. They have been inside it for about 2 weeks. I ended up getting 1-small blue spotted ray, 1 leopard shark 6 inches, 1 coral cat shark, 7 inches, 1 medium niger triger, 1 medium blue jaw trigger, 1 snowflake eel. They all seem to like each other. For the meanwhile.......
