Hi, I have had my Yepezi ray for about 3 month now and she is in with 4 large discus and 5 clown loaches, doing amazing!! and I was wondering if I could worm my discus with Kusuri Wormer with her in the tank. It says I can on the packet but i'be heard some horror stories. Should I just trust what it says or do a half dose? Any comment/suggestions ?? Ta
