Purchased a matted file fish 4 days ago to help control aiptasia. He eats mysis shrimp, nori and flakes but has so far shown no interest in aiptasia or other corals as some have experienced. I have read that it can take them several weeks to get an appetite for aiptasia. What are most peoples experiences. Even if it does not eat aipatsia it is still a cool fish. I would have done berghia again, but have tried it before and they work, but eventually die off and aiptasia eventually come back.
