I have 100+ Balloon Molly fry in a fry tank. One batch is 9 days old, and the other is 6 days old. Right now they look like any other Molly fry, long slim bodies. At what age should I expect to see them taking on more of a balloon shape? I expect a percentage of them might not develop into balloon, but a percentage should. (using my experience with chicken genetics anyway). Just a curious question.
