Bob Merrit gave a report in BKA newsletter No. 456, Sept.2003. Rainwater was used for breeding. Over a 2 week period 22 eggs were collected on a sample of Java moss. These were picked off into another container & floated in the tank. Most eggs hatched at 75°F in 20 days. Fry were fed newly hatched brine shrimp as a first food. |
