I just got an Engineer Goby last weekend. I've always wanted one because they remind me of an eel. Mine is a little guy that's about 4" in length. It's just starting to switch from it's juvenile colors to some more mature colors. Anyone on here have experience with them? It ate like a pig right after I put it in the tank, but I've only scene it once in the past few days. I was able to snap a quick pic, but it never stops moving so its a crappy one. Thanks for the input.
