Like all fish they will do their best to find what they need and sometimes adopt to aquarium food but ultimately they will start to go downhill if their specific food needs are not met.

I'm not claiming to know anything that's for sure just speaking from experience here. My kole is the nicest one I've personally ever seen. He doesn't really go for nori... all his algal needs are from the tank with most of that from the rocks. I've certainly had the glass get dirty many times and yeah you see all the sucker marks all over it but he still prefers to graze the rock for whatever reason.
