FeedingAncistrus should be fed mainly on vegetarian foods. Prepared foods include algae wafers and spirulina based sinking food. Vegetables such as courgette/zucchini, and (English) cucumber are an excellent addition to the diet, along with the odd, small amount of more meaty foods.
CompatibilityA good complement to most aquariums, they are not aggressive to other species. Males may fight over territory if kept in too small a tank.
Suggested TankmatesAppropriate with most community fish that aren't overly big or aggressive.
BreedingAll Ancistrus species are cave-breeders, where the male looks after the eggs and young fry.
