Cystein treatment for 12/04/13 (18d) and 24/04/13 (6d) egg masses. When opening the egg mass for 18d many juveniles poped-out  and thus received the cystein treatment directly.

01/05/13

Many juveniles (18d) burst because of the cystein treatment. I will need to fix this stage again. Otherwise, the earlier 6d embryos look fine.
