Neon Goby with a Purple Psuedochromis?

[salefen]

I have a Purple Psuedochromis right now and he seems to be pretty aggresive. He will chase some of the other fish around but it's not a constant thing. He just wants to show his dominants occasionally. Does anyone out there keep a Purple Psuedochromis and a Neon goby together. I would like to get a neon goby but I would hate for the Psuedo to harass it to death. thanks
