The common hatchetfish gets to about 1.5 inches in size and likes to be kept in a small school of 6 or more. A 20 gallon aquarium that is fully cycled with peaceful tank mates and lots of top level swimming space would be good to start with. The will eat small insects, worms, flake food, thawed and live foods. You also need to have a good fitting hood (or lower the water level) when keeping hatchetfish. Take your time when introducing them to your tank.
Spend an hour or more doing a slow drip acclimation and feed them a couple of times per day and they will reward you with lots of activity.
