THANKS, I would love to get my hands on some sleepy cod right about now. They are in the same genus (oxyeleotris) as the marble goby and share many traits one being teeth. Opposed to the spotted sleeper aka water cow from the genus (eleotris) who are often confused with marble gobys and are not as closely related or simular.That is a beast, so solid. I kept a couple sleepy cod before similar no where near as beastly though.
