Tank 1 — Display/Breeding
Main tank where proven breeders live. Handful of top adults — no overcrowding.
When females become gravid, move them to Tank 2 before birth.
Tank 2 — Birthing/Fry
10-20 gallon tank for birthing mothers and young fry (0-6 weeks).
Female gives birth, returns to Tank 1. Fry grow here with no predators.
Tank 3 — Grow-Out
20-30 gallon tank for fry 6 weeks to 3 months. Space for color development.
Sort by size and quality. Cull weaker fish, promote best to display tank.
Tank 4+ — Strain Preservation
Optional: dedicated tank per strain to prevent cross-breeding.
Serious breeders maintain 5-10 tanks, each with a pure strain.
