My new clown goby has been hiding for the past couple of days. At first he was less shy. He came out today and I noticed his belly was sunken in. He hasn't been eating much. I have seen him eat some and I just thought since he was so small maybe he didn't need as much food. I feed flakes in the morning and frozen brine at night. I also add DT's live phytoplankton. His tankmates are an oscillaris clown and a bangaii cardinal. I've read that I should try live food. Is it too late? What can I do to keep him from starving? What kind of live food is best? Any other suggestions?
