Breeding the wolf's glassfish

Not known to have been bred in captivity; probably spawns like Chanda ranga (adhesive eggs among plants).

Full species page

Step by step

Pairing

A group of 6 or more.

Breeding tank

A 300 L tank with plants and a brackish tendency.

What starts it

Warm water, live food and large tank.

Eggs and young

100-300 eggs; hatch in 24-48 hours.

Raising the fry

Feed infusoria, then baby brine shrimp.

Common mistakes
  • Small tankmates
  • Soft acidic water
  • Overcrowding
Setup blueprint

Home setup

One breeding tank for the wolf's glassfish, drawn to scale from the breeding guide.

A plan from the breeding guide and an adult size of 20 cm. Tank shape is a standard 2 : 1 : 1.2 box, at least 6 adult lengths long. Check each step in the guide above.

Setup blueprint

Business setup

A 135 cm rack for breeding the wolf's glassfish in numbers.

    Heat the room or each tank · 18–25 °C

In total: 3 tanks, about 1,500 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.

Male or female

No reliable external differences are known; adult females are probably fuller-bellied when ready to spawn.

Can I breed it in my tank?

  • Use a separate small tank with a sponge filter and spawning mops, so the eggs aren't eaten.
  • Takes some experience.

Day-by-day plan

Typical for egg scatterers

  1. 14 days beforeCondition the parents

    Feed live or frozen food twice a day. Keep males and females apart if you can.

  2. Day 0Spawning

    Eggs are scattered over mops or fine plants, often at first light. Remove the parents straight after.

  3. Day 1Eggs hatch

    Most eggs hatch in 1–2 days. Keep the tank dim and remove white (fungused) eggs.

  4. Day 4Free swimming, first food

    Fry use up the yolk and start swimming. Feed infusoria or liquid fry food several times a day.

  5. Day 8Baby brine shrimp

    Switch to newly hatched brine shrimp or microworms. Start small, daily water changes.

  6. Day 21Crushed flake

    Add finely crushed flake. Sort fry by size so the big ones don't eat the small ones.

  7. Day 60Ready to move

    Most small fish reach about 2 cm in 2–3 months and can join the main tank.

A general guide for this breeding type. Days change with temperature and species.

Simulator: guided

Stage 1 of 7Condition the parents

Feed live or frozen food twice a day. Keep males and females apart if you can.

Simulator: try it yourself

Set up a virtual breeding tank and see what would likely happen.

No spawning
  • Without live or frozen food the parents aren't in breeding condition.
