New to reef tanks but have a lot of experience in freshwater and maintaining reef tanks but not setting them up (I work at an aquarium store). I wanted some opinions on a potential stocking list for a 120 litre tank (30 gallons) (not including the sump). I was thinking 1 rainford's goby, 1 bicolour blenny, 2 peppermint shrimp and 1 six line wrasse. I would be adding the shrimp first and the 6 line wrasse last to minimize aggression. I'd also have some snails, and I plan to seed the tank with copepods before adding any fish. I'm planning having mostly sps corals, but I'll start with lps and softies of course for at least a year until the tank is ready for sps. Are there any problems with my plan? If it is relevant I live in Australia.
