I learned a valuable lesson this morning when I checked my newly stripped Cichlid fry; make sure you snap the lid on the breeder box. I thought I did and put a rock on top of it to make sure it stayed put and let it hang in the main cichlid tank. I woke up to only 10 fry instead of 25. Apparently they had swam out the top and got gobbled up by the adult cichlids.
