Puffer in community tank?

I have a 40 gallon breeder freshwater community tank, and I was wondering if I could add any species of puffers. Currently the inhabitants are rummynose tetras, kuhli loaches, Pygmy corydoras, a king tiger pleco, and an opaline gourami.

I was thinking pea puffers or maybe red eye red tailed puffer(either species under that name). I have a back up 20 gallon tank with a clown pleco if I need it as well. Is there any chance I could keep puffers? Other species that might work?
