Peppermint Pleco is a catfish, so the pairing works best when the planting style supports how that fish uses space and cover.

Amazon Sword reaches about 50 cm tall by 40 cm wide and is usually rooted in substrate with nutrient-rich substrate preferred. That makes placement and anchoring more important than simply adding a larger bunch of stems or leaves.

In this pairing, the useful plant values are line-of-sight breaks and spawning sites. Place it where Peppermint Pleco can actually use that structure instead of hiding the plant where it cannot do much.
