A lot of people consider silver dollars as tetra's. They get big enough to not be eaten by ghost knife fish. Should be kept in a 75 gallon Min IMO and that's for the smaller species.

I have 7 Congo Tetras who are beautiful. They live in a community tank with no problems. I don't think they'd fit in the mouth of a BKF

One must always consider the eventual mature size of fish, and if properly maintained this knifefish species will attain close to 20 inches. It is very timid and quiet, but still a natural predator that is nocturnal so any fish under 6 inches may well get eaten. Good tankmates are angelfish, discus, and some of the medium but peaceful South American cichlids. And of course the larger (for aquaria) catfish.

The tank must be large, at least 5 feet in length, and 2 feet in width (front to back). The knifefish is inflexible and must be able to turn around in the tank. This sized tank would accomodate one knifefish, plus suitable tankmates. With this large a tank, a group of the afore-mentioned angels or discus would be stunning, and since all of these fish prefer very dim waters and occur together naturally, a true biotope aquascape is one possibility, with plenty of wood and branches. Plants, considering the dim light, would be restricted to Anubias, Java Fern and Moss (unless one wants to be truly authentic with an Amazonian aquascape) for submersed, but floating plants which would further dim the light would be ideal.

The aquarist is one who must learn the ways of the biologist, the chemist, and the veterinarian. [unknown source]

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]
