Food

How to feed the Scrawled filefish?

It is a species of omnivorous fish. It is very difficult to feed. Its natural diet consists of algae but also invertebrates such as sponges, anemones, Hydraires, fire corals, tunicates... In aquariums, try to feed it this way and make contributions with live nereis, krill, mysis, artemia and mussel flesh. Seaweed (spirulina, nori), spinach and salad will also be appreciated. You will also have to sacrifice soft corals or anemones to be able to feed it properly.

It is very slow to feed. As a result, food competition is a real daily danger for it.
