Goldfish, Koi, FH, all man-made breeds..

Sometimes makes me wonder why people like goldfish/koi/FH/albino so much... those fishes don't really interest me. I've always liked wild form fishes. The wilder the better. My dad keeps goldfish and I think he's wasting a perfectly good 3 feet tank for a bunch of goldfish. However, it's my dad who got me into keeping fish in the first place and it's him who provided me with all my first knowledge and equipment to keep fish. I don't think I would be in the hobby if my dad didn't keep arowanas and goldfish and had spare tanks around. So can consider owe it mostly to them. My opinion is.. whatever fish it is, hybrid or whatever, it plays a part in perpetuating and spreading the hobby and deserves a level of respect. Who knows what an empty tank for a FH will end up being for after the FH fever is over.
