tamer they are the more likely they are to be seen. My fire eels are like puppydogs. always flitting out to see me when I walk into the room. They handfeed earthworms and frozen bloodworms. my TT after 1 month is still very shy though we are working on being buddies. earthworms are the greatest bribe I've found, he comes out and grabs it from me then darts back. also if you have a spiney in w/ your fire. the fire may also be aggressive towards it which is why it's hideing, not from you. but from it's tankmate.
