ive been trying to do research on the tire track eel and its been going alright between MFK and google but one thing i havent found was their growth rate.the tire track eels sold at my lfs are about 4".i am interested in one but a 4" tire track eel could not go in my 150 right away,it would have to grow out a bit in one of my smaller tanks and i just wanted to know how long it would take to reach,say,12".
