Remove adult fish after eggs are laid to avoid egg predation.
Caring For Fry
Fry hatch after about 24 to 36 hours. They are very small and need tiny food like infusoria or liquid fry food. Feed small amounts several times a day. Keep water clean and stable to avoid stress. Use a gentle filter or sponge filter to protect fry. Increase feeding size gradually as fry grow. Avoid sudden changes in water conditions or temperature.
