Down arrow Husbandry Information
Feeding This genus feeds on wood, and should have several pieces, preferably several kinds of wood to chew on. Aside from wood, a mainly vegetarian diet is recommended, prepared food such as algae wafers and fresh vegetables, such as courgette (zucchini) and tubers such as potato or sweet potato (yams).
Furniture Rock piles are optional and wood tangles are a must. Plants are not vital and will be nibbled or destroyed.
Suggested Tankmates Works well with most types of peaceful community fish. Can be somewhat territorial towards conspecifics, but given enough hiding spaces, a group can be kept in a suitable size aquarium - roughly requiring a 30 x 30cm area per fish.
Breeding Unreported.
Breeding Reports There is no breeding report.
