Both are suited to freshwater, so salinity does not add an extra planning problem.

Zebra Pleco (L046) does not put unusual pressure on this plant compared with harder fish-plant combinations.

African Onion Plant has low cover density, high uproot resistance, and tough / leathery leaves. It can also help with breaking up sight lines and surface cover.

Zebra Pleco (L046) is a catfish, so the pairing works best when the planting style supports how that fish uses space and cover.

African Onion Plant reaches about 100 cm tall by 30 cm wide and is usually bulb / tuber on or partly in substrate with nutrient-rich substrate preferred. That makes placement and anchoring more important than simply adding a larger bunch of stems or leaves.
