My friend got out of sw so he gave me his 150 gallon tank. One of the fish he sez is a Engineer Golby. So I was going to research him a little but the pics I seen (like on here) show it as being black with white strips head to tail. Mine is black with yellow stripes top to bottom. Does have a Golby shaped head with the eel like body. Is there more then one type of Engineer Golby??
