Down 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.

Suggested Tankmates Appropriate with most community fish that aren't overly big or aggressive.
Breeding Unreported.
