Gigantic Ick Outbreak!!!

I had the same thing happen a few months ago. I would suggest that you do not use a super strong dose of something like malchite green/formalin. I did and it killed my silver dollar before getting rid of any ick. Apparently even though they have scales they are rather sensitive to the medication. The pictus are also sensitive to malachite/formalin. Unfortunatly I know of nothing else that gets rid of ick effectively. I've heard of people using salt and copper solutions but have never tried it my self. The most inportant thing to would be to keep the tank medicated/ remove any carbon filters or highly porus rocks and change a good bit of the water daily also keeping the temperature high is a good idea because it speeds up the life cycle of ick.

Once all of the white spots are gone keep medicating the tank at lower doses for a full week. Ick is a parasitic protozoan and has many life stages. Even though the white cysts are gone there may still be some free swiming protozoa.

Raise your water temperature to 82 degrees. I keep mine there and have not had ich since. Planted tanks like a warm temp as well.

fwiw
