Diamond Goby in my tank?

[critofer]

hey guys,
I have really want a diamond goby but heard a 29 gallon is way to small for one. Plus, i have a little yellow watchmen goby too, but he just stays under this one rock and will barely leave it. my question is, could i keep a diamond goby in my 29 gallon? Will my watchmen and diamond fight with each other?

Thanks guys

I have had 2 Diamond gobies in my 29 gallon FOWLR, (not at once)

they did fine until they both swallowed crushed coral.

make sure you have fine substrate, rock for them to burrow under, and you spot feed them in front of their burrow. (unless you have live sand with lots of copepods)

My substrate is livesand, i dont know if it is crushed coral but it does look fine, not large pieces. Would my watchmen goby and the diamond goby fight though? my tank is only like a month and a half old.
