Ikan Manfish Bertelur: Angelfish Pairing & Breeding Guide for Malaysia

When ikan manfish bertelur, the pair cleans a flat surface, lays neat rows of 100 to several hundred amber eggs, and then guards them. Angelfish (Pterophyllum scalare) are egg-layers that breed readily in Malaysia's warm water, but most first spawns fail because young parents eat the eggs or the eggs grow fungus. This guide covers how to get a pair, the spawning setup, what to do when parents eat eggs, and how to hatch eggs artificially with ubat biru (methylene blue).

Ikan Manfish Bertelur: Breeding at a Glance

Stage	Typical timing at 28–30°C	What you see
Pairing	Fish reach maturity at about 6–12 months	Two fish split off, defend a corner, "lip lock"
Cleaning	1–3 days before spawning	Pair picks at a leaf, slate or pipe
Spawning	1–2 hours	Female lays rows of eggs, male follows to fertilise
Hatching	About 2–3 days	Eggs turn into wriggling larvae stuck to the surface
Free-swimming	About 5–7 days after spawning	Fry leave the surface and look for food
Re-spawn	Every 1–3 weeks if eggs are removed	Pair cleans again

Warmer water speeds everything up. Typical Malaysian room temperatures already sit in the angelfish breeding range, so most homes don't need a heater.

Step 1: Getting a Pair

Buy a young group, let them choose

Angelfish pick their own partners. The most reliable method is to buy 6–8 juveniles and grow them together in a 3-foot (akuarium 3 kaki, about 155–180 L) tank. As they mature, one pair will start claiming territory and chasing others away. Move that pair to their own tank.

Buying a "proven pair" from a seller is faster, but ask whether they have spawned recently and whether they raised eggs or ate them.

Ikan manfish jantan dan betina: how to tell

Angelfish are notoriously hard to sex by looks. Guides you'll see online include:

• Males often develop a bump on the forehead (nuchal hump) and a steeper head profile.
• Females often look rounder in the belly when full of eggs.
• The breeding tube is the only sure sign. Just before spawning, the female's tube (ovipositor) is thick and blunt, while the male's is thinner and pointed.

Two females can pair up and lay unfertilised eggs that turn white within a day. If every batch turns white, you may have two females.

Step 2: The Spawning Tank

Item	Recommendation
Tank	2 kaki deep (60 × 45 × 45 cm, about 100 L) or larger; height matters for angelfish
Filter	Sponge filter on an air pump, so eggs and fry aren't sucked in
Spawning site	Slate, tile, PVC pipe or a broad plant leaf (Amazon sword, Anubias), angled upright
Water	Stable, clean, treated with anti klorin; soft Malaysian tap water usually suits angelfish
Temperature	27–30°C, normal Malaysian room temperature
Light	Moderate; keep the tank away from heavy foot traffic

Condition the pair for 1–2 weeks with high-protein food such as frozen bloodworm, artemia and quality pellets. Do small, regular water changes; a slightly cooler change after conditioning sometimes triggers spawning.

Step 3: Spawning and Egg Care

Once the pair starts cleaning a surface, leave them alone. The female passes over the slate laying eggs, and the male follows to fertilise them. Healthy fertilised eggs are clear to amber. Unfertilised eggs turn opaque white within about 24 hours and often grow fungus that can spread.

The parents fan the eggs with their fins and pick off white ones. Good parents can raise their own fry. Many young pairs don't, at least not at first.

Why Parent Angelfish Eat Their Eggs

This is the number one complaint from Malaysian hobbyists, and it is usually not a sign of a "bad" pair. Common causes:

1. Inexperience. First-time pairs often eat several batches before they learn. Give them 3–5 attempts.
2. Stress. Tankmates, people walking past, a tank near a door or loud TV, or a sudden light switch-on.
3. Infertile eggs. If the male is young or the "pair" is two females, eggs go white and get eaten.
4. Hunger. Underfed parents are more likely to snack.
5. Water quality. Ammonia or nitrite spikes trigger stress eating.

Try covering the sides of the tank with paper, removing tankmates, or adding a mesh divider so the parents can see but not reach the eggs. If they keep eating every batch, switch to artificial hatching.

Step 4: Artificial Hatching with Methylene Blue

This is the method many local breeders use because it gives far more fry per spawn.

1. Prepare a hatching container: a small tank or a 5–10 L container filled with water from the parents' tank (same temperature and chemistry).
2. Add an airstone on very gentle bubbles, placed near the slate so water moves over the eggs without blasting them. This replaces the parents' fanning.
3. Add a few drops of methylene blue (ubat biru) until the water is light blue. It helps prevent fungus on the eggs. Follow the product label. See our guide to ubat biru for fish.
4. Move the slate or leaf with the eggs into the container, keeping it underwater the whole time.
5. Keep it dark and stable. Remove any eggs that turn white and fuzzy with a pipette.
6. Change some water daily once the larvae hatch, using water from the parent tank, and let the blue fade as fry become free-swimming.

A breeding and isolation box hung inside the parent tank also works for hatching and the first weeks of fry, because it shares the main tank's water and temperature.

Step 5: Raising Angelfish Fry

• Days 1–5 after hatching: fry live off their yolk sacs and hang on the slate. Do not feed yet.
• Free-swimming: feed newly hatched baby brine shrimp (artemia) 3–4 times a day, or fine fry foods as a backup.
• From about 2–3 weeks: add crushed flakes and micro pellets.
• Water changes: small, daily or every other day, always dechlorinated. Fry are sensitive to chlorine and ammonia.
• Grow-out space: dozens of growing angelfish need room. Plan a grow-out tank or a buyer for the juveniles before you have hundreds.

Malaysian Tips

• Power cuts: an air pump on a battery backup protects eggs and fry during outages.
• Heat waves: if a room climbs past about 32°C, add a cooling fan or chiller to keep the breeding tank stable.
• Fungus risk: warm water grows fungus fast, so remove white eggs early.
• Selling extras: Malaysia has many angelfish breeders, so ordinary juveniles have modest demand. Distinct strains (platinum, koi, marble, veil) are easier to rehome. Never release extras into drains or rivers.

Frequently Asked Questions

Berapa lama telur ikan manfish menetas?

Pada suhu biasa di Malaysia (27–30°C), telur ikan manfish biasanya menetas dalam masa 2–3 hari. Anak ikan akan mula berenang bebas lebih kurang 5–7 hari selepas bertelur.

Kenapa ikan manfish makan telur sendiri?

Biasanya sebab pasangan masih muda dan belum berpengalaman, ikan stres, telur tidak disenyawakan, atau kualiti air kurang baik. Beri mereka beberapa peluang, atau pindahkan telur dan tetaskan sendiri dengan ubat biru.

How do I know if angelfish eggs are fertile?

Fertile eggs stay clear to amber and develop dark centres. Infertile eggs turn opaque white within about a day and may grow fuzzy fungus.

Can angelfish breed in a community tank?

They can, but eggs and fry are usually eaten by tankmates, and the pair becomes aggressive while guarding. A separate tank gives far better results.

How often do angelfish spawn?

A healthy, well-fed pair can spawn every 1–3 weeks if the eggs are removed. Give the female rest periods so she doesn't get worn down.
