Amazing, but i don't want to sound mean or anything but it would be best for them to stay there they obv like it! lol i dunno just seems unfair to take them from their i know we keep fish in tanks which have been taken originally from the wild but they are bred for a aquarium but still amazing work
Well, I don't want to seem mean, but in all reality, it would be best for them to NOT stay where they are. Although from the sounds of it they are unlikely to leave the hot springs (the tropicals anyway, the koi may), introduced exotics have a way of taking over any piece of environment that they can get even the slightest of footholds in. It's quite likely that before the intrusion of these fish, the hot spring had other, NATURAL, inhabitants that were wiped out by the introduced species ability to outcompete them for food, territory, or (in the case of the africans) outright aggression, or were simply eaten by the koi and other larger predators.
It is a lovely place, and cool for what it is, but the fact of the matter remains that those fish don't really belong there. Better to see them there than ill treated in some uninformed fishkeeper's tank, but I can't say that I think they should stay there. Besides, from the looks of it, most of these fish are, or are descendants of fish who were, bred for the aquarium. They're no different than the fish in your lfs.
Chuka: For future reference, wet your hands before handling the fish (they look dry in those pics, though if i'm wrong, sorry) because dry hands can damage their slime coats pretty well and expose them more readily to disease.
