Hey Guys, my Naso tang is laying sideways, he just got up a few minutes ago flapped for a little bit didn't move or leave the substrate, and then kind layed a little sideways again....none of the other fish are affected including a Regal Tang, and 2 clownfish....I can pick him up with the net with no resistance...he will swim but its like he has no choice but to fall.....any idea whats wrong with him. Hes been doing awesome for the past week almost, use to hang out at the top waiting for food and all that good stuff.
