How many gobies

[MBVette]

How many gobies do you think I can have peacefully in my tank.

I have a 210g tank with:

A yellow watchman/pistol in my tank for awhile
a diamond sand sifting gobie

Do you think I can get away with adding another gobie/pistol shrimp combo?

Other than those two I dont have any other bottom dwelling fish in my tank. Do you think its possible to get a new set of gobie/pistol or will it cause problems with my current gobies.

I'm not real sure on compatability issues with the watchmans but in a 210 surely there is enough real estate for them to reside in different areas of the tank. No way I could ever find it now but I remember one guy keeping multiple Randall's and Yasha gobies together in a system.
I just looked in my fish guide and is does not recomend keeping two watchmans together unless they are a known pair.

I didnt really want another watchman. Maybe a yasha or something. But I just love the pistol shrimp, as he is the most entertaining thing in the tank. I could sit for hours watching him move the sand around.

I would go with a Randalls and a Tiger Pistol in a 210 (its what I have in mine). They are far larger than the tiny Yasha and Candy pistol and wont be so easily lost in such a large system, much more outgoing too. My Randalls will even defend his turf against the biggest wrasse and tang in my tank, something the tiny Yasha would never do.

Im pretty open to the pairing with the tiger pistol, as long as its not a watchman as I have one already. But Im just concerned that with 3 gobies that there might not be enough room.

Each gobie is basically in the corner of the tank, so if I add another pistol I would try to add it to the middle of the tank, but Im sure it will find its own spot.
