Introduction
Breeding cherry barbs is a rewarding experience for freshwater hobbyists. You won't need complicated equipment, but raising the fry takes preparation. Adults will happily eat their offspring, so protecting the eggs is your number one priority.
Cherry barbs (Rohanella titteya) are peaceful, hardy fish that breed readily in the home aquarium. They are egg scatterers: the female releases eggs while the male fertilizes them, and the eggs stick to plants, moss, or other surfaces. There is no nest and no parental care.
Success comes down to three things:
- A prepared spawning tank
- Well-conditioned adults
- The right first foods for tiny fry
Telling Males and Females Apart
| Male | Female | |
|---|---|---|
| Body | Slimmer | Fuller, rounder belly (especially with eggs) |
| Color | Deep, vivid red when mature and in breeding condition | More muted: tan or light red |
Color alone isn't reliable, since lighting, age, diet, and variety all affect it. Judge by body shape and color together.
Step 1: Choose Your Breeding Fish
- Pick mature fish (about 6 months or older) that are active, eat readily, swim normally, and show no signs of disease.
- Use one male to two or three females. A male will chase a lone female relentlessly, which stresses her and can prevent spawning.
Step 2: Condition the Fish
Condition the group for 1-2 weeks before moving them to the breeding tank.
- Feed two small meals a day.
- Mix quality flakes or micro-pellets with live or frozen foods such as daphnia, brine shrimp, or bloodworms.
- Remove uneaten food after a few minutes.
- It's working when females visibly fill out and males color up deeply.
Step 3: Set Up the Breeding Tank
| Item | Recommendation |
|---|---|
| Tank size | 10 gallons minimum; water 6-8 inches deep |
| Lighting | Dim |
| Spawning material | Fine-leaved plants (java moss, hornwort), spawning mops, or a spawning grid/mesh just above the bottom |
| Filtration | Gentle sponge filter; it won't suck up eggs or fry |
| Temperature | 77-82°F |
| Water | Soft to moderate, near-neutral pH |
The eggs are slightly adhesive, so plants and mops catch them well. A grid is the single most effective protection: eggs fall through the gaps where adults can't easily reach them.
Stability matters more than perfect numbers. Raising the temperature a couple of degrees with a partial water change using slightly cooler fresh water can help trigger spawning.
Step 4: Introduce the Fish and Watch for Spawning
Move the group in the evening and leave them alone. Spawning usually happens in the morning, often shortly after the lights come on.
Signs spawning is near
- Males color up intensely and chase females
- Fish spend more time darting through the plants
- Pairs swim close together while the female scatters a small batch of eggs and the male fertilizes them, repeating over several hours
A healthy female can lay a couple hundred eggs, though first-time spawners often lay fewer. If nothing happens after a few days, check temperature and conditioning, then try a cooler partial water change.
Step 5: Protect the Eggs
Remove the adults once spawning is finished, usually the same day. They will eat the eggs, so don't wait. With a grid you can leave them in a little longer, but removing them is still safest. Don't handle the eggs unnecessarily.
Step 6: Hatching and Egg Care
Eggs hatch in roughly 24-48 hours at breeding temperatures; warmer water speeds this up.
| Egg condition | Appearance | Action |
|---|---|---|
| Fertile | Clear to slightly amber; tiny eyespots may develop | Leave alone |
| Infertile / dead | White and opaque; may grow fungus | Remove promptly with a pipette or tweezers |
Fungus spreads to healthy neighbors, so keep the water clean with gentle movement. Indian almond leaves or a small amount of methylene blue are common methods; research whichever you plan to use before spawning so you can act quickly.
Step 7: Raising the Fry
Newly hatched fry live off their yolk sac for the first 3-4 days, hanging on plants and tank walls and barely moving. They don't need feeding yet. Once free-swimming, follow this schedule:
| Age | Food |
|---|---|
| Days 3-7 | Infusoria, liquid fry food, or finely powdered fry food |
| Week 2 | Newly hatched baby brine shrimp or microworms, plus vinegar eels |
| Weeks 3-4 | Crushed flake or micro-pellets alongside baby brine shrimp |
| Week 5+ | Finely crushed flake and small frozen foods |
Feed small amounts two to three times a day. A round, orange-tinted belly means the fry are eating well.
Water quality
- Fry are sensitive to ammonia and nitrite, and uneaten food fouls water fast.
- Do small, frequent changes (10-20% a few times a week) with a slow siphon.
- Keep the sponge filter running and take care not to siphon up tiny fry.
- Sort fry by size as they grow; larger fry can nip or outcompete smaller ones.
Moving to a community tank
Wait until the young fish are around an inch long (roughly 10-12 weeks), healthy, and eating normally. Check your tank mates first: larger or predatory fish can still eat juveniles, and shy fish can be bullied. When in doubt, wait a few more weeks.
Troubleshooting Common Problems
| Problem | Cause and fix |
|---|---|
| Not spawning | Check maturity, conditioning, a 1:2 or 1:3 ratio, and temperature. Try a slightly cooler partial water change to simulate rainfall. |
| Eggs disappeared | The adults ate them. Use a grid, dense plants, or a mop, and remove adults sooner. |
| Eggs turned white | Infertile or dead. Remove quickly and check water quality. |
| Can't find fry | They're tiny and hide on leaves and tank walls. Look closely and avoid disturbing the tank. |
| Fry dying | See likely causes below. |
Why fry die (most likely first)
- Food too large, or not enough food (starvation)
- Ammonia or nitrite from poor water quality
- Overfeeding
- Sudden temperature swings
Cherry Barb Breeding FAQ
| Question | Answer |
|---|---|
| Are they easy to breed? | Spawning is easy. Raising fry takes more work: protecting eggs and having the right first foods ready. |
| Do they lay eggs? | Yes, adhesive eggs scattered among plants and other surfaces. |
| Do they eat their eggs? | Yes, so separate the adults after spawning. |
| How many eggs? | A couple hundred over a session for a healthy female; first-timers often fewer. |
| How do I improve fry survival? | Protect eggs, remove dead ones fast, keep water clean, and have tiny food ready the day they start swimming. |
| Can albino cherry barbs breed? | Yes. |
Final Thoughts
Breeding cherry barbs is straightforward if you prepare ahead: condition healthy fish, set up a tank with a spawning grid or dense plants, remove the adults after spawning, and have fry food ready on day three. Have everything set up before the fish spawn, especially the fry foods. A little preparation makes the difference between a handful of survivors and a tank full of healthy young cherry barbs.
