Hi to everybody.

thank you very much

Never, never use malachite green! It is highly toxic to amphibians. You need to treat the tank with several treatments of activated carbon (charcoal) and water changes to get rid of the malachite green.

Keep the newts in the other tank. Keep them cool and clean, and they may recover without any other help. There is not much else you can do.
