So, I have some plants in my tank (4 different plants in a 55 gal). One of them (yeah, unfortunately I don't know what its called, which might be my first mistake), has multiple holes in about 5 of the 25 or so leaves. It has a darkish purple quality on some it and its really pretty. I'm wondering if our otocinclus are eating holes in it? Why would that only happen with one plant? Anybody have any ideas?
