Conch climbing aquarium glass

[falter]

Along with "Repo", our rescue clownfish, we also rescued what we were told was a fighting conch. I'm not sure about that.. it basically has a long, narrowish shell.

It has been living in the tank without issue for over a month now, but tonight for the first time I spotted it climbing the glass to graze on algae there. I read online that this may be a warning sign of starvation.. do conches pretty much never climb glass unless they have to?

Mine does this all the time, I think it can mean they are starved, but also they don't understand walls very well, so they just go one way looking for food, not really understanding its a glass wall instead of a rock covered in more food.

I have 2 fighting conch and one strawberry conch in my 112g display. I have never seen them climb the glass. If I saw mine done that I would try to get it some food. I assume they may graze on nori so you could try that.
