| Other Information: |
The larvae all dropped off at around 14 days. This is said to be around the time they reach meta. Many of them died due to the fact that they stuck to the side of the tank before that time as well. They tend to park if given the chance. Next time I will be introducing enriched BBS and turning up the temp. |
