Nowadays the fish eat fine, they are very active yet they have these symptoms:
- Yoyos and tetras keep flashing a lot on daily basis.
- Ancistrus breaths heavily/rapidly.
- Tetras have swollen/red gills.
I've tried changing water more often (up to three times a week 30-50%) but it doesn't seem to be helping. No rotting plants in the tank. Tested water quality and there are no problems with it. I also use water conditioner and the tank has extra aeration to help fish to breath. Thus I think I've ruled out everything that could be the problem with water.
Then I started searching for possible diseases, thought it could be either Gyrodactylus or Dactylogyrus and treated the tank with praziquantel. --> It didn't have any effect.
Anyone have any idea what could be the problem? Here's some photos of the fish. See anything that could be a sign of a disease?
Little yoyo's both sides:

Little yoyo 2's left side (this yoyo has lost a bit colouring but it could also be because she/he is the one that is being chased, she/he keeps flashing more often than others though):

Ancistrus (her head seems a bit greyish/dusty but I don't know if it's just her normal colour):
