Seen an 18in a while ago. Peaceful and similar to bgk. No aggressive tankmates. Better in groups but need a large tank.

What’s the minimum tank size for them?

IME, knives don't use as much space as most fish their size, but I'd say an absolute minimum of 125g long term just because apparently trumpets get pretty big.

I’d say a 180 lifelong. As it should be able to hit the 20in mark.

Depends on what you mean by trumpet knifefish...some species of Rhamphichthys grow to 3 ft. They can be aggressive toward each other, but they really can't do much damage as they don't have any teeth.
