tt track/fire eel

When my prior tank crashed I lost my fire eel. He was my favorite fish. I finally found another one at the store that seemed outgoing, but the lady netted the wrong one I think. He or she is super timid and just hides all the time. My old one would take worms from my hand. This one runs away...

Hey guys i just got a 100gallon tank, im waiting till it's completely cycled to add my baby in there, problem is im debating wether to get a tire track eel or a fire eel, I'm not new to the hobby, a little rusty, but not new. In your experience wich grows quicker? Besides frequent water changes...
