I waws at the locasl fish store which is The Fish Store and more and in one of their show tanks they had white cheek gobies which cuaght my eye. I asked the man about them and he said that they liked a ph about 7 and soft water and that a sand substrate is goodd becuase they sift through the sandd. I was wondering if any body could give me some more info on these gobies or if anyone has any expierence with these gobies. thanks.
