I have a what was sold to me as a Beau Gregory..although now no one can identify it..He was the last fish put in the tank about a month ago. Shy at first, but now stakes his "sleeping hole". A little picked on at first-mainly during feeding but everyone is happy again9hippo, perc, 3 chromis, 2 yellow watchamn's(rarely seen or even budge for that matter) and a diamond watchman goby(serious hole digger! great guy!) Over the past couple of dats he has chosen a front corner in the tank and goes down to the sand and "blows" it away to create this shallow spot in the DSB-he'll nose dive into it..push the sand out with his body-all day long. There is a large rock "protecting" it...What the heck is he doing??
