Hey guys I am new to the reef keeping world and figured what better place to learn and ask questions than on a forum especially when it's local. So here it goes, I have a 20 gallon long setup right now with some CUC and 20 pounds of live rock and sand. It's been running for about 2 weeks now and I will be getting some fish for it probably Thursday. I am considering a pair of ocellaris clowns. My question is what do you all recommend as a first fish?
