that fish is not bred in farms, and not in the hobby. My friend had a group he brought back from Thailand a few years ago, other than that you're not going to see them. They are very cool, look like giant macropodus or betta fish!
I noticed. I've seen them here and there and I've seen some people recently give theirs to their LFS but I was just too late to get a hold of them. I'm still looking and I'll continue looking. Please get the word out to your friends if possible.
