Cave spawner; the male guards the brood. Has been bred regularly in aquaria.
Grow out 6-8 juveniles and let a pair form; keep the group in a well-oxygenated, stable tank.
100-200 L tank with strong flow, many caves sized to the fish (PVC or ceramic tubes), and very clean, warm water.
Cool water changes, increased flow and a seasonal drop in temperature, plus rich protein feeding.
The male guards a small clutch (5-30 large amber eggs) in the cave for around 5-10 days until they hatch; the fry carry a big yolk sac.
Fry stay in the cave until the yolk is gone, then feed on sinking algae wafers, blanched veg and crushed flake. Keep nitrate low.
Seen from above, males are slimmer and less stocky than females. Odontode growth is often similar in both sexes, though some older males have more on the pectoral fins.
Typical for cave spawners
Give one cave per pair or female, plus a varied diet.
Eggs are laid inside the cave and guarded, usually by the male.
Eggs hatch in 3–7 days depending on the species and temperature.
Feed baby brine shrimp and crushed food. Plecos need wood and vegetables.
Fry grow on in their own tank.
