Do not know what has happen to my 2 discus.
I deworm also still the fish doesnt want to eat.
I starve them few days like 3 days after my short trip also doesn’t want to eat.
Not eating it does not mean worm only.
The fish may be sick.
If the water quality is bad, the fish will not eat too.
They do not like the food you feed them.
If you love your fish, you should try many alternative ways to make them
Try to feed them with live food like worm or bloodworm after water change.
