Does anyone have any experience with a large group of Clown Gobies?

The wife and I are looking for a fun fish that's small and relatively inexpensive to fill out the livestock in our tank. We just got one of these guys in out tank (Yellow variety) and it appears to be a good candidate. We'd like to get a few more, probably max out around 5 in all. The tank is a 75g, we don't want any squabbling so if that's not enough territory in anyone's opinion we'll gladly scale it down.

Well I've got 7 various types of gobies such as:

yase hase
hectori
circus goby
red cap
golden neon
atenna goby
randals

all in my 24 gallon nano cube, don't worry, I've got a 20H sump with a Aqua c remora HOB skimmer as well.

I'm planning on doing more gobies, a pair of firefish, and two male flasher wrasses (with a tight closing lid).

I'm not worried about several different species, I'm talking about 3-5 of the same fish.
