I just bought 3 otocinclus fish. However, I don't know what the fish usually eat. Can you tell me the food that is suitable for otocinclus? Then, is algae also one of the types of food?
Otocinclus usually feeds on biofilms that grow on driftwood and other plants that slowly decay in the aquarium. In addition, it will also eat green plants and algae. One thing you need to know about Otocinclus is that it is the best algae-eating fish.
