Is there something wrong with her gills?

Hi all, can anyone tell me whether this fishes gills are anything to be concerned about? I also believe this fish may have swimmers bladder ? It seems to always float back to the surface no matter what. I’m not sure whether this is related to the fishes reddening gills but if anyone could let me know that’d be great

The fish is a balloon molly and their body is less than half the length of a normal molly. This causes their internal organs to get squished up and they have a lot more internal problems.

Mollies and other common livebearers from Asia usually have gill flukes and intestinal worms. The fish has stringy poop and this is often a sign of worms.

Gill flukes can damage the gills and cause them to go redder than normal or real pale pink if the fish is running low on blood.

Floating about can be a swim bladder problem or air in the intestine. With deformed fishes like balloon fish and fantail goldfish, the air gets ingested when they feed from the surface and trapped in their intestine. If the fish is fed a variety of foods (in particular frozen and live) they don't normally have this issue. The way to test for a swim bladder problem is to stop feeding dry food and only give the fish frozen or live food for a week. If they stop floating about then the issue is air in the intestine. If it doesn't improve after a week without dry food, then it has a swim bladder problem.

Section 3 of the following link tells you how to treat fish for intestinal worms. Some deworming medications (Praziquantel & Flubendazole) also treat gill flukes.
