! And they're much more unusual than the usual livebearers, cichlids & corys Awesome, I've never kept killi fish but i've always been interested. The only thing is I've never seen them for sale where I live (or in any city near here) could I order them online without paying a ton of money for fish that arrive dead? Lol

. Despite being around for centuries in countries like Japan, they don't seem to be that common yet in the aquarium hobby in the west, so i would personally recommend them as an easy started breeding fish.
