I have a chance to get a great deal on a small zebra moray and im pretty positive im gonna take it. The setup would be a 30L (hes less then 8" long and will be in there alone, I know im gonna need a bigger tank soon, just working with what Ive got) with a 10g sump and a mag 3 powering it. The tank with be FOWLR and like I said just him. Is it live and die important that I have a skimmer at setup or is it something that I can wait a few weeks on and just do water changes?
