Hi

Wondering if anyone can help me out.

I have Aquamaster Fluke and Tapeworm Tablets, I was thinking of dissolving a tablet and soak some blood worms in the medication to feed to my discus,as i have one big male blue turquoise that i recently bought breathing from one gill ( on and off ). All of my other discus are healthy and happy and i don't want to treat the hole tank because of the Cory cats and plants.
I have never medicated my discus and i have had them for 8 months now.

Has anyone tried this?

Is it effective?
