i dont have pictures, but the lfs had two dwarfs and right away you could tell one was yellow while the other one was just brownish/red. the one i saw didnt have a large head like the one in the picture though. i told the LFS to hold onto the yellow dwarf while i found out some more info on it to make sure it was reef safe. also showed me that it was eating these flakes they had
i have a full grown YWG, a bue damsel with yellow tail, and a royal gramma. all of them are always hiding unless its time to eat
