Molly blew out her rear end

Hello everyone! I found your online forum searching for help regarding my female molly. She’s about a year old, had several babies in that time. Recently I noticed her rear end looking bulgy… she was having normal bowel movements and still having fry come out. I woke up a few days ago to her whole rear end blown out and red. Looked like someone bit her rear end off and two holes are now one hole. Water parameters are all normal, we don’t have any mean bitey fish in the tank either. She’s one of the largest I have also. I thought for sure she was going to die but the hole seems to be healing, and she’s still pooping and squeezing a fry out of there here and there. She’s eating and swimming acting normally. The hole is still as large as before but no longer red. Anyone have any suggestions? I did add some salt and some Paraguard just as a preventive measure. Can this actually heal?

Looks like a prolapse. Not sure how to help them heal, but daily small water changes should help a lot for preventing infection.

 

Well small update… she’s still going strong. She still has that gaping hole back there but she’s eating, swimming, popping out fry here and there like normal. The male sailfin isn’t really sure how to breed her at this point but that’s probably a good thing. I think it’s healed enough she can function but I don’t see it going back down to normal either. I have been doing water changes per your suggestion and making sure she’s comfy. She’s looking at me like “mom make him stop” cause the male keeps trying to breed her but he can’t lol. He has other females tho so he’s not harassing her too much.

 

Well, good on the harrassment part! I would just keep a good eye on it, it may go back in eventually, i just don't know how. Not like with humans where you can do some damage with preparation H.

 

Yeah I mean it appears she blew an o ring for sure lol! But it isn’t raw anymore and she’s playing and swimming like normal. I don’t think she’s going to be getting pregnant anymore so once the babies in there are born I think she will be done.

 

Update… my molly passed away yesterday. She had seemed fine… she was looking heavily pregnant. I did a small autopsy and discovered that the sack containing at least 50 ready to be born babies had either healed and scarred closed near the anus or it was twisted where the babies couldn’t make an exit. It was clearly obstructed after her injury. So sad! She had been acting normal, eating, swimming, socializing. None of the babies survived either. Such a shame.
