I have read a couple of the threads about with eggs. One of my otto's has a small air space where the eggs would be. It does not have trouble swimming and seems fine, however the other otto's do not have this air space.
Otto with possible problem

bk828's second picture shows the eggs, my otto has an empty air space the same shape and size as that. The skin is clear so you can see its empty. Ill try to get a picture this weekend.
