Sure. You can just BARELY see a faint outline if you know where to look. He somehow managed to get behind the tank and is sitting next to the skimmer and heater. No worries the heater is seperated from him by glass and the skimmer is seperated from him by plexiglass. He squeezed himself in between the two. Ooh he just moved
What corals are you planning for and also what's your lighting? Here's a shot of my tank, I just added the kessil A150W and if you were looking to upgrade your lighting then I would strongly suggest this one. Your tank is lookin good btw.
