So a few days ago I noticed a little bit of Java fern floating on the surface of the tank. I thought nothing of it because one or two of the leaves have tears in them so I assumed that was the cause.
However, yesterday I noticed betta mouth-sized chunks out of one of the Java fern leaves. These chunks are at the side of the leaf and one is in the middle. There's no floating pieces of leaf at the surface of the tank either so I'm assuming my betta has actually eaten some of the leaves.
Is this normal behaviour and would this cause my betta any harm?
I've read that Java fern doesn't taste pleasant to fish so I'm wondering why my betta is eating it?
