Care is basically identical. Have you ever looked into Slobbering Cats (formerly Goslinia Platynema; IDK the revised Latin)? Now THAT'S a cool catfish that flies under most people's radars.
Brachyplatystoma platynemum.
They're quite closely related to tigs and jurs. I think my next write up will be on Brachyplatystoma if I can find the time.
I thought lei is more aggressive than jardini, no? IDK much about lei, never had one.
Jars are way worse. Honestly, neither a tig nor a jur would match their ferocious reputation. The metaphor is really only valid if we're considering husbandry.
