freshwater eels?

Question

I was just given a fish tank today with some goldfish and some eels. The eels are about 7 inches long and are about 3/4 inch tall. They are brown and their tail fins are broad. I know for a fact that they aren't tire tracks or spiny eels. They also have whiskers (six that go around their mouth) and they sometimes suck on the side of the tank. They are moderately aggressive when fed brine shrimp, but for the most part are mild mannered and stick together.

Any ideas of what they may be?

Thanks!!

Answer 1

Sounds like those would be a dojo (weather) loach: http://www.fishlore.com/profile-dojoloach.htm

Answer 2

Sounds like Dojo loaches, or maybe horseface loaches. Lucky you, loaches are awesome fish.
