i would like some, do you still sell them?

its definitly a rendahls, i have a few, they are great but not as hardy as the tandanus and salmon cats.
how big is he?

i have a few tandanus catfish in my 6fter,including a rather large one about 30-40cm.
they are pretty invincible and i think you could get away with just about any regular water temp and ph.
i have one in a very alkaline tank (cichlids) and a few in an acidic tank.
they are all eating happily and ...

i would say NO!
in a few months it will easily be large enough to eat the gourami in one gulp.
they only go well with large aussie natives, american cichlids and other large exotics.

i feed mine anything it will eat, i think they eat more than they should and have to rest a while to digest.
they are awesome fish though but they get big!
