I ddn't remember what a hatchet fish looked like so I looked them up on google images and saw those that are very vicious looking with big teeth and Iwas thinking that had to have not been what they meant. lol
But I did see the ones I think you are talking about, they look cute!
It would be fun to have other fish with my bettas, but the tank size is an issue with that.
