Adding Clown Plecs

[San O Fisher]

I am in the process of changing out a tank and completely reworking my set up to add more hidding places. I would like to add 2-3 clown plecs, but will they get along with my current stocking in a 55 gallong tank, slightly planted with plenty of wood and rock.

3 pictus cats
1 RTBS
4-5 Otos
5-6 Cherry Barbs
6 Tiger Barbs

I am slightly concerned about the shy nature of them around the pictus cats.
