I wouldn't reccomend that stuff for other than ornamental fish. I think it's a proven carcinogen too. Really bad news for the biofilter.

I also read somewhere that centrarchids are sensitive to either methylene blue or malachite green. Can't remember which.

And keep in mind many of the chemicals and some antibiotics that are used on ornamental fish, are not approved for use on other species, especally those that will be consumed.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
