Best bet is to drip acclimate it to your system, turn off or turn way down your power heads, if you haven't yet this may be a good time to put guards on your powerheads. And place him in the tank where you want him. Wait for him to attach and turn back on your powerheads. Where you place him isnt going to matter a whole lot because if hes not happy where you choose, he'll walk around until he find a spot hes happy with. I wouldnt feed him directly as he will be stressed from the move. If your lighting is sufficient you dont have to directly feed them. I've never directly fed mine
