what sort of plec and what sort of gourami?
the clown will outgrow your tank and needs to be kept in a group, you mentioned before that you have oscars so i assume you have a nice big tank for them, you may be best getting a few more clowns and putting them all into the larger oscar tank, if needs be you can grow them on in the 200l tank until they're big enough to not get eaten by the oscars
the plec is quite small roughly 5cm, its dark brown with spots not sure of the proper name for it. the gourami is a pearl blue one
