HumaaHuma Biting at Glass

[caymanlovers]

We have a HumaHuma (or HumuHumu) that recently started biting at the glass sides of the tank. Looks like play but wondering if anyone else has observed this behavior.
Chemistry is OK and tank has been established about 6 months.
Any ideas?
Thanks!

Yeah... my humuhumu does that occasionally. I don't think that's a problem. They do that on rocks also... I'm guessing that wanting to bite something hard is in their nature (like how rodents has to keep chewing on things to wear out their teeth so it won't over grow). But~ that's just a guess. My humu humu was doing that for a while and caused no problems...

your huma's are eating algae. It's nothing to worry about.
