Mostly, the goby behaviour is good. They munch away on the sand...dig under the rocks...and generally keep the tank looking very nice.

Unfortunately, from time to time, the male goby (I think the larger one is the male) seems to get obsessive about building a gigantic mound of sand that covers entire rocks and corals. If left undisturbed, I think he would attempt to move the entire sand bed into one large pyramid.

Here's a photo of his handiwork. The scary thing about this photo is that it took him ONLY 2 HOURS TO DO THIS. Only 2 hours earlier, I moved all this sand away.


Now..the reason that I am blaming HIM for all this is that the female has disappeared again. It seems that when the female holes up (last time it was 3 days), the male starts this obsessive building behaviour. I don't know where the female is, but I strongly suspect she is under the pile trying to tend to some eggs.
