I went to a lfs near my house and i saw 2 different kinds of fish i haven't seen very often and i don't know what they are. I don't have a picture of them but i can try to describe them. The first one was long and thin with a scaly body like a pleco, it was blackish brown and it had a long "nose" and it sucked on the side of the tank. I have no idea what it was. I was gonna buy it, then i decided not to since i don't know anything about it or it's care. The second fish i saw had a body like a fire track eel, except it was light colored, something like a light yellow with faint bluish bands around it. It had a kind of long "nose" and a big mouth undeneath it. Any ideas?
