I have a school of 8 river hatchets in my 180 litre community. They are also known as 'common' hatchet fish. However - they are actually rarer than the marbled version! They don't always stay at the top - but most of them are always hanging around there. From what I know - these fish are relatively hardy and, from my experience, VERY peaceful. They are a lot smaller than their marbled cousin - but lack the pattern.

I have a tank of approximately 1500 L with many different fish, including a breeding pair of bristlenose catfish, many of their offspring, 2 albino bristlenose catfish (I'm hoping one of them might pair off with one of the regulars offspring), 3 discus, 12 rummy nose tetras, 20 neon tetras, 7 Siamese algae eaters, 4 silver sharks, 3 glass catfish, 2 albino cories and some others. But my heartache at first only was the river hatchetfish. I added 3 to my tank only to come back the next day and find that 2 of them had jumped out of the smallest holes in the top of the tank. So with only one left I covered the holes. Three months later it is as hardy and big as ever. Today I added 2 more for it. They are great fish to keep. I will keep adding till a shoal of eight. I do find the older one I have likes to sometimes venture midtank, but never for too long. They seem to like the stream at the top of the tank.

For those not in the know; the silver hatchet is a great fish. Loves the top of the tank and will jump out of the tank. Be sure to secure lid. This fish is a jumper. Also very peaceful.
