I have an American Cichlid tank that also houses a bichir and 2 bn plecs. The Oscar and 2 severums are showing ick. I was going to use Mardel Coppersafe until I read that it will harm scale less fish. It sounds cruel but my main concern here is my bichir. I've ordered some API Aquarium Salt as I was advised this will not harm the bichir, but the plecs I am not sure. The medication will arrive in a few days and I want to make sure I am doing the right thing. Thanks.
