My 5 big discus fish died last week, what happened they didn’t eat for 7-9 days after that they died one by one, the incident was very pailful to me, then i surfed your site and came to know about WORM, Wow we can de-worm a discus?
Internal Parasite in the intestine
1. Treated with metronidazole. 500 mg in ten gallons as a day-long bath works well.
2. Do it daily for a few days in fresh water each day.
3. If your fish are eating then mix Flubenol in food to feed them.
