Mixing Clown Gobies

[DracoKat]

I am debating on getting a few clown gobies for my 20 gal tank.

I read they can be aggressive with their own kinds..

but what about mixing different types, like Lemon Goby and Green Goby? Panda Goby and Yellow Goby? Would they get along or chances are they'd bicker too?

I had a pair of yellow and they were great. Not sure I would do more than two of any specific one. As far as mixing the species in a smaller tank, do it at the same time and provide plenty of areas for them, they should be fine.
