Guppies breed easily. A plan keeps tanks stable and fry healthy without sudden overcrowding.
Starting ratios
- Trio approach: 1 male to 2–3 females reduces chasing stress.
- Separate grow-out: move fry to a second tank once they’re 2–3 weeks old.
Feeding for controlled growth
Feed fry 3–4 light meals daily (powder or baby brine). Keep adult feedings modest to prevent explosive fry counts and water issues.
When fry arrive
- Provide dense plants or spawning mops if you want higher survival.
- If you need fewer fry, keep more open space and feed moderately.
- Cull early for bent spines or weak finnage to keep lines strong.
Rehoming responsibly
Offer extras to local hobbyists, stores, or clubs. Ship only when temperatures and routes are safe, and follow your state’s biosecurity rules.
