Oh yikes. This
could be two things.
Swim Bladder:
- Swim bladder usually results in a fully active fish, but their swimming is almost as if they are full of air.
- This is caused by overfeeding. How often do you feed your fish and how much (and with what)?
- You can feed them peeled and boiled peas, but there isn't much else you can do.
Ammonia Poisoning:
- This is what I am leaning more towards since this is most common.
- Lethargic fish that tip when they swim, laying on their stomach in the gravel, facing head down, facing nose up when swimming.
- This could also be accompanied by ammonia burn which is red dots on their stomach and gills.
More pictures and your water parameters can really help.
