So I've had my blue gig for over a month and over the past week my haddoni has taken it upon itself to move all of the way across the tank to root himself down right next to him. Both look fine and do not seem to recoil from touching each other. Is this anything I should be concerned about? The haddoni had been in the same place for over a year so I'm pretty sure that move was a result of the gig being added to the tank.
