Has been bred in aquaria, but very few details are recorded. The fry are presumably tiny and need plenty of algae. Most fish sold are wild-caught.
Keep a group with a mix of sexes and feed lots of algae to bring them into condition.
40 L tank with fine sand, dense plants, some tannins and a gentle current.
Cool, fresh water changes and plenty of biofilm and algae feeding.
Tiny sticky eggs are laid on glass or leaves in small batches; adults do not guard them.
Fry feed on biofilm and powdered spirulina; very prone to starvation, so keep a mature algae-rich tank.
One breeding tank for the zebra otocinclus, drawn to scale from the breeding guide.
Water: 21–25 °C · pH 6–7.5 · sand bottom
A plan from the breeding guide and an adult size of 4.5 cm. Tank shape is a standard 2 : 1 : 1.2 box, at least 6 adult lengths long. Check each step in the guide above.
A 120 cm rack for breeding the zebra otocinclus in numbers.
In total: 4 tanks, about 240 L of water. A litre of water weighs about 1 kg, so check that the floor and rack can take the weight.
Sizes are worked out from the breeding tank in the guide. Tanks fit a standard 120 cm rack when they can; bigger tanks go on their own stands.
Adult males are 5-10 mm smaller than females and have a conical urogenital papilla behind the anus, which females lack. Males also have a flap on the top of the first pectoral-fin ray. Females look fuller.
Typical for egg scatterers
Feed live or frozen food twice a day. Keep males and females apart if you can.
Eggs are scattered over mops or fine plants, often at first light. Remove the parents straight after.
Most eggs hatch in 1–2 days. Keep the tank dim and remove white (fungused) eggs.
Fry use up the yolk and start swimming. Feed infusoria or liquid fry food several times a day.
Switch to newly hatched brine shrimp or microworms. Start small, daily water changes.
Add finely crushed flake. Sort fry by size so the big ones don't eat the small ones.
Most small fish reach about 2 cm in 2–3 months and can join the main tank.
