I have never heard of it happening. But I dug this up on a internet search.
Captive breeding is possible but this probably won’t happen unless the fish are kept in a very large tank. In this case, that means 500 gallons or more. The pair will usually lay their eggs on floating plants and the male will aggressively guard them until they hatch in 6 or 7 days. The fry should be moved into a rearing tank and fed baby brine shrimp until they are large enough to take other foods.
