Diamond Goby

[wavemaster]

I have decided I want to add a diamond goby to my 29 gallon biocube. I think they look cool and I want to have white sand. Has anyone kept one of these in a similar size tank to mine? Some say 30 gallons while others say 50 gallon minimum. I will be looking for the smallest diamond goby I can find.

I do not mind my sand being stirred up, but I have not touched my sand for a year. I am worried when I add it, toxins will come up from the sand. How worried should I be about adding this fish? My LFS will be getting them in next week. Would it help to gradually stir the sand myself over this week before getting the goby next week?

Any other tips on caring for this fish? My sandbed is about 2'' deep and tank has been running 6 years.
