Which goby is best for sifting sand...

Well...i have both types of goby's in my aquarium, and it is a rare occurance to see the watchman sifting sand..The other is doing this on a near enough constant basis..

lol...Its like the watchman goby is watching the other and wondering " sheesh, what ARE you doing? Do you know i just pooped there?"....

I also have both, and they both sift sand. The sleeper has a bigger mouth and is a bit more active at it.

Hahaha!

I had both in the past and the Gold Head was constantly sifting much more than the Diamond. I also happen to think it looks better and its blue streaks would sometimes seem to glow.
