Can you actually breed fish in minecraft?

only axolotls, sort of. regular fish like cod, salmon and tropical fish can't be bred at all, they just spawn in water and despawn. if you want a tank full of them, scoop them up with a water bucket and place them where you want, a bucket keeps the fish (tropical ones keep their pattern too). what people mix up is that you feed axolotls a bucket of tropical fish to breed them, so it looks like fish are involved in breeding when it's really the axolotl.
