Swords My Pleco Will Not Strip?

[Electric Warrior]

Does anyone have any suggestions for sword plants that a pleco will not strip to pieces? It seems that everything I have tried, my bn just destroys. He doesn't really bother anything else, just swords. It's the regular old bleheri that he seems to prefer and anytime I try and add them to my tank, the leaves are stripped clean in a few days. The only one he hasn't seemed to have bothered with is the red devil, but that is right next to my apistos cave, so that might have something to do with that? Do they normally like eating swords?

In my experience plecos will eat any plants with leafs weather the leafs are small or big. when the plecos are smaller they usually don't eat through the leafs its normally the larger ones that will tear through plants in my experience.
