Other Details
Other Information:	The hatch from this report was tumbled in a flask from the time of spawn, exposed to light. A subsequent egg tumble was done in an inverted 2L bottle tumbler (top cut off and put into the bottom as a base) and protected from light and this tumbling method worked significantly better (100+ hatched) and the eggs hatched in the evening instead of all day. Eggs hatched on the fourth night after spawn (counting the day of the spawn as the 1st night).
