I've had both Tire Track and Fire (really cool) eels in community tanks, both with alot of luck. For the Fire eel, I dropped an old fashioned clear-glass, long neck bottle into the tank. It took him a couple of days to find it, but when he did, he loved it. I was able to see him great, and I could feed him blood worms, sent down a rigid 1/2" tube, right to the bottle opening...pretty funny to see the other fish unsuccessfully attacking the blood worms on the way down! Eels are a really cool addition to a tank - go for it.
