Alright so I'm sitting here just looking at my tank, as I always do lol, and I noticed that some of the leaves on my jungle Val seems to me kind of beat up. It looms as if something is eating the ends of the leaves. It's only a few leaves that look beat up but I was wondering what could be causing that? I know my otos like to hang out on the leaves but I don't think they'd be eating them. What's could be the issue?
