I'm doing a mix of flakes, straight mysis shrimp, and then a frozen mix of brine, mysis, spirulina etc....There is no reason they shouldnt like it. I talked to the LFS about what they were feeding them, and am doing the same. He explained that since they were in a small tank, with like 20 plus clowns all together they might need some adjustment time being just 2 of them in a 90 gallon. but now 9 days seems a little long IMO.
