Recently my discus’ tank start showing white worm look like things moving on the glass and also lots of them in water, my local aquarium shop told me it’s probably cause by over feeding, normally I feed fish with dry food, but one of the new comer doesn’t like the dry food, so I start feed with frozen blood worm, this is where the problem starts, could you please tell me how to get rid of those parania and how to prevent it happening again in the future, and can i still feed my discus with frozen blood worms?

1. No description about the tank; bare, planted with live plants, decorated with artificial plants?
2. If it is a bare tank, change water then do parasite and bacteria treatment.
3. Your tank contains of parasite and bacteria.
4. Add salt after water changed.
5. Over feeding can cause endless problems. Feed the amount they can eat. It is not because of bloodworm or dry food. It is because of left over food that causes trouble
