Who is eating my glosso?

[Tresbling]

I recently added 4 red eye tetras and 3 ottocinclus to my tank, and since then, chunks have disappeared out of my glosso and sometimes whole leaves!

I suspect the tetras but i know they ottos are fond of salad.

What to do? Any ideas?

I don't think ottos would be capable of taking chunks out of any plants, even if they wanted to.

What else do you have? It may be coincidence and it's something else that has just discovered that it's tasty.
