Hi, I am starting a new 20 gallon tank and wanted to put a school of hatchetfish in it, but I am concerned about having them try to fly out the tank every time I change the water or vacuum the gravel. Has anyone had any experience with these fish?
They are quite the jumpers.
make sure you have a tight fitting hood on their tank.
Having some sort of floating plant seems to help calm them down.
Also, I have found turning their tank light off, while leaving a room light on, is the best way to work ontheir tank.
