alrite 2 questions, im switchin from fresh to salt with a 30g. It will be FOWLR, i was talkin to a guy at the lfs and he said that i wouldnt need a protein skimmer unless i got a bigger tank or went with corals, is this true? im on a pretty tight budget. And what kind of fish should go in here? i was thinking about some clowns, possibly a small tang, im not sure how fast they grow but if not that fast i could upgrade in a little while. Any other ideas? Thanks
