Sexing Like all members of the genus, males grow elongated interopercular odontodes during the breeding season. Males develop noticeable odontodes along the dorsum (back of the body) as well. Males develop small pointed genital papillae, whereas mature females will have large, rounded, swollen papillae. Additionally, gravid females have noticeably wider bodies between the pectoral and pelvic fins when viewed from above, compared to males.

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 Females lay between 25 and 40 eggs, around 6mm in diameter. Males care for the eggs and fry. After approximately 7 days the egg-sack is consumed. The fry aren't particularly sensitive, but should have access to soft wood to chew on; this combined with algae tablets and a little bit of high protein food will have them grow quickly and are sexually mature after around a year. They will spawn in ceramic caves, but seem to prefer caves made from bamboo, but they will chew this type of cave to bits. Spawning takes place at a temperature between 26 and 29C and a conductivity between 200 and 400 uS/cm (around 150-300ppm TDS). Circulation needs to be good but not strong.
