I am thinking of starting my first fish tank while i am at college. I want to get one tire track eel to begin with. I will get some gravel and some rocks for them to hide, as i have read it will need this. i plan on keeping it in a 50 gallon tank and feed it earth worms. is there anything wrong here? is there anything i am missing? and how long will i be able to keep it in a 50 gallon tank. please respond as soon as possible with as much information as you can!!! thank you so much! -A
