Will a knight gobie eat a small mono?

Also, Will a mono Sebae be happy with an Argentinous as a tank mate?

Depends on sizes..It should be perfectly ok but the knights can be a bit agressive...

My puffer has been ok and he is about the same size as the goby. I think I'm going to get him and watch him for a little while. Maybe segregate him off until he gets a little bigger.
