Salt water newbie

If 20 is your limit, I would suggest that you get a 20 long. Awesome footprint and should give you a bit more space for more corals and one or two more fishes. I have also being into freshwater for like 10 years and started saltwater about a month ago and its going great till now. Small is not bad as long as you have proper filtration and do regular maintenance. The only downside I would say is that it limits your livestock to a "huge" extend!
