Is my conch starving?

[Ocean’s Piece]

So I have a conch and he completely eradicated my cyano issue on the sandbed within the first week. He’s been in there for a month or two now and I have noticed he has started to clean the rocks and the walls and glass more often. I know the way do this from time to time but does this mean he’s starving or that he’s just checking out spots he hasn’t eaten off of

As long as there is some algae for him to munch on and the tank isn't too young, he should be fine if you're concerned, strap a piece of nori to a place on the rock and he can munch

Ok I may do that. The tank is 8 months. Don’t know if you consider it young because that term is pretty relative in this hobby.

And there’s typically a light dusting of cyano but no more strands on the sandbed
