One of mine is pretty active at about 6pm onwards, the other is only active after about 10pm.
Heres a picture of one of mine, poking his head out the gravel. You can also see my baby Gibbiceps Pleco on the log next to him:

Here is my tire track I used to have.He was 11in.He would swim to the top of the tank and take a nightcrawler from my hand.But he jumped out of my tank.He was so cool,Never shy. I'm go to get another one soon.
I have a 16" tire track eel,maybe 2 yrs old.wait until hey hit the 8-10" mark and start feeding frozen krill.Mine has grown an inch a month since he could finally get the krill into his mouth.It makes things easy . Krill is the staple food of that tank because of my 14" silver arowana,my7" bichirand my snowflake eel.The tire track eel has actually passed my arowana as the largest fish in the tank.
I have about a 5-6 inch Zig Zag, 9-10 inch Tire-Track, and a 11-12 Fire eel. The zig zag is the only one that eats brineshrimp frozen and a lil frozen bloodworms. The tire track used to eat a lil bloodworms when it was new but now the fire and tire track only eat live Earthworms and Ghost shrimp.
