Wow I have to say that I agree 100% with Animal Guy on this one.Either an unfaded rt or a tx-FH. I think it's an unfaded RT as is.
if you replace with natural gravels, and have his water at 85 degree, and let him settle.. once hes adapted, turn on the light and show him the mirror till till he gets angry. I promise you will see another side of him. If your water is clean and established.
then take more update pictures!!
