Looking to add a catfish.....

[Hendre]

You could try Raphael's or 4 line Pimelodus

^^

Raphaels are the lazier of i remember correctly and pims are quite busy in a group, good suggestions

Thanks I will check both of them out

If you'd like a bigger cat, you could look into some of the bigger Doradids, like Megalodoras uranoscopus.

Bigger is better as long as it is safe..
The 4 line looks interesting.. I like the lima but a bit nervous . . I will look into the others you posted..

Pictus and four line pim might be a little too active and stress the plates too much.
