Hi and welcome to AA!!
First off is to do a lot of research on SW
fish and tanks. A good start is the articles section here on AA:
I'd start off by figuring out which fish you want to keep in your tank. Liveaquaria.com has a decent site as to the tank size fish will need. With SW
, you will need to take your time as you cycle your tank and add fish etc.
Do you know if you'll want a fish only tank (FOWLR
) or a mixed reef? If going the coral route, make sure to get reef-safe fish.
Good luck and feel free to ask questions!
