1. Choose a species you can house as adults
Start with adult size, temperament, water needs and expected reproductive rate. A species that is easy to spawn may be difficult to house once dozens of juveniles are growing.
2. Prove the system is stable
Use a mature biological filter, test water regularly and learn the normal range for your tap water and aquarium. Chasing an ideal number is usually less useful than maintaining appropriate, stable conditions.
3. Match the spawning method
Livebearers, egg scatterers, bubble-nest builders and cave spawners protect offspring differently. The tank layout should reflect the method.
4. Plan food and grow-out before spawning
First foods must be available when fry become free-swimming. A separate grow-out tank, spare filter and a schedule for water changes should already exist.
5. Decide where juveniles will go
Keep only the number you can house well. Confirm local shop, club or private-home options before repeated spawning.
