Hop to next section Husbandry Information
Feeding Ancistrus 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. User data.
Compatibility A 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 Tankmates Appropriate with most community fish that aren't overly big or aggressive.
Breeding All Ancistrus species are cave-breeders, where the male looks after the eggs and young fry.
