So, the man picked up some corals from a tank break in our local club. No big deal, they were dipped and placed in the 180. Now, here's the issue. He felt bad for the broken tank's clown pair. So, he took them -__- I already have a pair of baby Long Fins in our 180. The big clowns can't go in it. That leaves my extra 20G Long. I was going to set it up as a frag grow out before moving coral to the 180. I need ideas on lights, filtration, and a powerhead. I've never had a tank this tiny. HELP, I NEED AN ADULT. lol
