Is that molly pg or is it a balloon molly? I don't believe I ever saw any of mine get that "blown up" looking. I have two rather small bumble bee platies that never look pg and I have had them for a couple of months now. Every few days I will notice a couple of more fry. like maybe 1 -3 at a time. There is a good size betta in there, who may be getting a few, but so far I have 3 that have gotten too big for him to eat and a couple of others that are still working at it.
