Already 3 months the discus stomach is getting bigger and bigger each week. I have try change the food and give medication but it still no help. The fish is ok it have appetite to eat. Just the stomach
is getting bigger.
1. Possible there are internal parasites in the stomach.
2. The parasites multiply and grow bigger, then the stomach grow
bigger as well.
Apply Epsom salt in the tank for 24 hours.
You can repeat the treatment.
