Re: White stuff on the head

Ratin, I think you're on the right track with your water changes, but for Discus, it's just not enough. These fish are river fish, and they're used to a constant supply of fresh water. I've seen breeders in Asia change 100% of their water daily, no filtration at all, and their fish thrive. I'm not saying you need to go that extreme, but 30% daily is a good starting point.

I've been doing this for 20 years, and I can tell you that hole in the head is a tough one to cure, even if you catch it early. I'm not optimistic about this fish's chances, but I understand why you're trying.

For testing your water, I swear by the API tests. They're accurate and easy to use. I know some LPS stores test water for free, so that's an option if you don't want to invest in a test kit.

Let's be real, most additives like Melafix are just a waste of money. Clean, stable water is the key to healthy Discus. I'd ditch the extras and focus on getting your water changes up to par.

Re: White stuff on the head
Liz, even with low chances of success, would you still try treating the main tank or would you move the affected fish to a separate quarantine tank?

Re: White stuff on the head

I would move the fish to a QT and start treating it with Metro, 500 mg per 10 gallons, until a month after it appears to be cured. Daily water changes of 75% to keep the water pristine. For the community tank, I'd increase the water changes to 30% daily to prevent this from happening to the other fish.

Thanks for the great advice, I really appreciate it.

You're most welcome.
