Something not mentioned or understood. The pathogens living in tropical water courses are not all the same as those that live in temperate water courses. Fish in the tropical waters have ways to deal with the pathogens they must live with, just as temperate water fish have ways to deal with the different pathogens they encounter. This is one reason that governments like the US and Canada prohibit the release of any aquatic life form into local waters. The US Agriculture will stop any plant being imported (most of the time anyway, maybe always) into the US, and for very good reason. I'm sorry, but this whole idea is insane. There is no benefit whatsoever, and there is a terrible risk to the fish.
