Saw a blenny on recent trip to Bocas del Toro, Panama. Sorry no picture. The blenny or blennies I saw were white/biege in color. 1.5-2.5 inches in length. 2-3 large brown blotches on side. Sandy bottom. 20-30 feet in depth. Hanging out with what is best described as an upside down jelly fish. Easily approached. Anybody have a clue? Thanks. Steve
