Ask the seller what the fed it on.
Many eels take a few weeks to settle in, get them eating something that wriggles first and then mix that with similar looking food that doesn't wriggle, then mix in other foods...if not they will fixate on one particular food.
Many retailers sell these in volume that are wild caught or wild farmed, they rarely eat at the retailer as not there long enough and then down to us to train them to eat in the aquarium.
Mine was the same and now he is very thick and over 12 inches..I expect he will get over 24inches and more.
