The Engineer Goby, Pholidychtys luecotaenia, has a black body with a white horizontal stripe. They are very hardy and peaceful and can be housed with other peaceful fish in a reef tank setting, but may become territorial towards other blennies, gobies or dartfish in smaller tanks.
Gobies tend to stay mainly towards the bottom of the tank, burrowing and sifting through the sand. However, this goby is also a known jumper, so a tightly fitting lid is suggested. Diet should include a variety of frozen or live mysis shrimp and vitamin enriched brine shrimp 1-2 times daily.
so if ur afraid of an eel messing up your tank this guy is perfect he will get big and is eel looking but goby peaceful eh likes to dig holes and have a cave area under rocks
O.K. Not a very complicated fish.
This engineer goby remained visible for about three days. It was eating, then promptly disappeared! I am guessing he is being reclusive as most engineer gobies are.
I'll keep an eye out and update when he reappears.
I have bought several of this fish. Had one that lived 10 years in the same tank (55 gal.). I had another live three years in a 20 gallon. It is a simple fish, but fun to watch. And they are cheap!
moves almost like an eel but looks like a giant freshwater neon....they do dig so don't get a herd of them....mine "built" right on the front glass, so it is like watching an ant farm....
