Silver Hatchetfish Question

Hey everyone, I havea 38 gallon tankthat I am planning to stock with some peaceful South American fish. I am definetly going to put in silver hatchetfish. I think that they liked to be kept in groups of 5-6, but i was wondering if 3 silver hatchetfish and 3-4 marbled hatchetfish would shoal togeher and be happy. Planned tankmates will include 6 corys and 1 twig catfish. Other recommende tankmates would be appriciated. Thank you.

I would use one or the other.

As you already know they are jumpers. I used an egg crate top to prevent jumping. But when I did maintenance I would find a couple jumped out.

FWIW the are actually "true" flying fish by that I mean the "flap their fins" to get more air time.

interesting fish.

my .02

maintain Fw and marine system with a strong emphasis on balanced, stabilized system that as much as possible are self substaning.

have maintained FW systems for up to 9 years with descendants from original fish and marine aquariums for up to 8 years.

With no water changes, untreated tap water, inexpensive lighting by first starting the tank with live plants (FW) or macro algae( marine)

I happen to have both in my 115g tank, and they do not socialize cross-species. The marble hatchetfish all interact from time to time, and the silver hatchetfish interact from time to time. But never across species. They don't fight, they are quite compatible, but you need a decent sized group of each species.

And hatchets are always better with more. With marbles, I would not have less than 9 or 10. The Silver are fine with 7 or more. But in your 38g, which I will assume is probably 3 feet in length max, I would go with the smaller Marble Hatchetfish, and get a dozen.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
