Livebearer tank/Ich/salt question

[jonatheber]

I may have some ich in my tank. Some white raised spots showed up on two of my three Painted Glass tetras. I see NO signs of spots anywhere else. I also have a golden algae eater, a bunch of guppies and a few platys and mollys. As a preventative measure, I added aquarium salt - 1 TBS/3 gallons (46 gallon tank, 16 or so tablespoons).

1) Is that the right ratio for preventative measures? I'm not convinced I have it - I don't see ANY spots on any other fish.
2) I have a bunch of guppy babies. Is that concentration likely to harm the babies that are obviously much smaller?

Copied from one of @Colin_T 's posts;
"add 2 heaped tablespoons of rock salt for every 20 litres (5 gallons) of tank water. Keep the salt in there for 2-4 weeks. When you do water changes during this time, add salt to the new water before adding it to the tank so the salinity (salt level) in the tank remains stable."
Colin is our ONE of our resident genius, I'll look around to see if I can find an answer about if it could be harmful to fry.

If it is ich, raise the tank temp to 86 deg F and keep it there for 2 weeks. Salt can be used at the same time, but heat is the most important part.

I've used alt/heat treatment with newborn guppy fry in there, and they survived it fine. Livebearers are pretty salt tolerant, so that helps. Fish farms abroad often raise livebearers in brackish water in fact, and the heat is no worse than them riding out a heatwave in nature.

You wouldn't want to keep them at that temp permanently, but they can handle it much more easily than ich can.

More of @Colin_T’s advice:

“The safest treatment for white spot (Ichthyophthirius, aka ick or ich) is heat. Just raise the water temperature to 30C (86F) and keep it there for 2 weeks. Then reduce the temperature.”

I've platy fry that have had most of their lives at the high temp as I'm treating ich too. They are thriving. Growing lots & swimming about.
