Do you all live your lives like you were in the wild? Do you all run around naked eating fruit nuts berries with the occasional bit of raw meat? No I don't think many of us do... Until recently I had a very happy community tank with 2 blue yabbies, 2 plecs, 5 red cap orandas 1 siamese fighting fish and a few mollies. they all loved living together... that wouldn't of happend in the wild, Don't forget your animals aren't in the wild, they're captive, and in a small slice of water too. technically we shouldn't eat half of what we do as humans, but for me as well as my animals I believe variety is the spice of life... I had to part with the majority of my fish because they had grown too big, they had not got sick once in they're lives, no fin rot, no white spot, no fighting at all. Don't forget people, just because you can or should do something doesn't mean you should... how would you like to be kept in a 6x6 room and fed nuts and berries every day and a bit of raw meat every now and again? get a bit boring wouldn't it. wouldn't you like something different every now and again? Try looking at the Farm Animal Welfare Council 5 freedoms, Animals aren't just there for us to keep it's like the difference between a zoo and a nature conserve.
