Java fern, vals and anubias taste bitter to fish (or at least thats what it says in their profile, is I'm guessing why they don't touch them), even if they are herbivores, the worst that mbuna can do to those plants is uproot them.
I was hoping that if i keep them well fed maybe they'd leave the plants alone? I bought omega one spirulina flakes and kelp/spirulina pellets so hopefully that would work.
If they like the plant, they'll eat it despite you feeding them well, mbuna have no control over their appetite, overfeeding is one of the ways how they get the bloat.
