I will give it a dip.
The Diamond Goby is great! Sometimes, I purposely burry some food in the sand to keep him digging in the sand. the water will get murky, but it will go away eventually. Sometimes I move the sand around myself, becaouse he likes making sand wholes, when I even out the sand, the water gets murky.
He is awesome!
The midas blenny is a bit of a tank bully though, He rarely nips my goby and Cardinal. I need the camera back to take pics!!!
