I know that now, it's not that hard taking care of discus fish, also as I have heard on the forums. But I think discus fish are on the pricey side is not only for their colors, but this is why: I remember, maybe 6 or more years ago, I had a fish book, and it said that discus fish should only be kept by experts, and that's how I viewed it until recently. It's because technology has made fish keeping a little easier, and safer for the fish, and now discus fish are easier to keep. Who knows, maybe their price will go down a little. But I think they are still a little delicate, yes?
