when i have fish that like to hide i take their hiding spots away until they get used to it. then i give the spot back and usually they dont hide anymore, if they do i scare them out until they give up.
You could try removing all decorations...plants....drift wood....etc....

Strong lighting can also make fish hide. If your tank lights are too intense or on for too long, many times fish will stay in hiding.
