multiple sand sifting gobies

[CindyKz]

Hi,

I have a 180gal tank with a 2 ish inch sand bottom. My diamond goby does a good job stirring the sand near his burrow but he rarely ventures to the other side of the tank.

I'm considering adding a tiger goby. Would they kill each other? I don't think they are likely to starve, the diamond takes frozen food and there isn't much competing for food in the sand bed other than a few nassarius snails and a conch that doesn't seem to move around much.

Thanks,

Cindy
