Two wilds will be fine . For feeding , it depends on the fish . I have found some clowns are really picky . I feed mine a combination of different flake foods [Formula One , Two , and Prime Reef are some good flake foods] , frozen Brine and mysis shrimp , frozen squid , Cyclopeeze, Krill to name a few . I hatch live Brine shrimp once and a while [just because they like it] . Try a few different foods to see what they like . I have 4 Ocellaris clowns that love algae base foods and others that don`t .
