My other hobby is angling and I was wondering if any of the diseases of native fish such as KHV, SVC,Dropsy etc are capable of infecting tropical species or vice versa ?
In addition to tropicals, I also keep North American native sunfishes. Almost all diseases that affect temperate freshwater fishes can also infect tropical fishes and vice versa. Any wild-caught fish will likely harbor some parasites. The wisest course of action would be to quarantine any of your catches in a separate tank for at least a couple of weeks, while treating them with a general anti-parasite medication. (Seachem's Paraguard is excellent and quite safe, and it also has some effect against fungus and bacteria.) I perform the same quarantine while treating with Paraguard for all new acquisitions, whether purchased or wild-caught.
