I am currently working on setting up a 60x18x30 140 Gallon, and I was planning on getting a Tire Track Eel. Are Tire Track Eels very active or not, I know they need a tight lid, and will the Tire Track Eel use the height as well or just the footprint of the tank. I would like to have a peaceful tank (No Cichlids Except German Blue Rams) so please feel free to mention any fish that will go well with the German Blue Rams, and the Tire Track Eel.
