Once a long long time ago when I was a fish novice around 14 years old. I saw ich for the first time and diagnosed it as such. panicked I went and bought the first ich treatment I saw some little capsules you open to release malachite blue in the water. I had several fish and three of which were botia modesta. At the end of the week the ich was about gone, but the botias looked like they were mutants. Their eyes were enlarged to the size of green peas their skin was in a horrible shape. Later I found out the malachite green kills loaches and other scaleless fish by being absorbed through the skin and in effect killing the fish. All treatment of ich is somewhat poisoning the fish. But our concern as fish keepers is to what extent. Loaches usually require a different approach than malachite Blue, it also stains your silicone a greenish blue. For loaches I would recommend copper salt like Aqua-Sol. It works great. I do know of people that treated their loaches with a half-dosage of MB and turned up the water temp., and it worked. But after what I saw happened to my loaches I could never do that to them, they look like they were in excruciating pain. Copper salt is much cheaper too.
