1-Make a breeding trap system that you put into the tank rather
than moving the fish.
2- I hope you are feeding more that frozen artemia -- not a balanced
diet. If you are using non-enriched artemia, you could even have
fatty acid problems (insufficient omega-3 fatty acids).
3- 16 months is on the back side of the reproductive curve for this
4- Give them more that an hour to get going.
