Hello! I have been keeping freshwater aquariums for over 3 years now, and ended up working at Petco (I know...) because of it. Anyway, I haven't really had the urge to keep saltwater until now. There's this maroon Clown that I have taken a liking to at work. It's become super protective of a tiny little bubble tip anemone. Anyway, I have two major questions. Firstly, what tank size would I want? I'm reading anything from 30 gallons up to 50 for what I want to do. Secondly, what do I need to know going from fresh to salt?
