Aquarium Plants That Don't Need Substrate — Epiphytes, Moss & Floating Plants No substrate? No problem. Whether you're working with a bare-bottom tank, a gravel setup that doesn't support rooted plants, or simply prefer the flexibility of substrate-free planting, there's an entire world of stunning aquarium plants that never need to be buried in soil, sand, or gravel. At Canton Aquatics , this collection brings together every plant we carry that thrives without substrate: epiphytes that attach to rocks and driftwood, mosses that cling to any surface, and floating plants that live entirely on the water surface. These plants are perfect for bare-bottom tanks, quarantine tanks, hospital tanks, breeding setups, and aquariums with large substrate-disturbing fish. Three Categories of Substrate-Free Plants 1. Epiphytes — Plants That Attach to Hardscape Epiphytic aquarium plants grow attached to rocks, driftwood, and other hard surfaces. Their roots grip onto surfaces rather than absorbing nutrients from soil — they feed through their leaves from the water column. This makes them incredibly versatile and easy to rearrange. 2. Mosses — Cling to Any Surface Aquarium mosses attach to virtually any textured surface using tiny holdfasts. They create beautiful, natural-looking coverage on driftwood, rocks, mesh, and even tank walls. No substrate involvement whatsoever. 3. Floating Plants — Surface Dwellers Floating plants live entirely on the water surface, dangling roots into the water column. They're the ultimate substrate-free plants — they don't even need hardscape to attach to. Best Substrate-Free Aquarium Plants Anubias — The Premier Epiphyte Anubias is the most popular epiphytic aquarium plant — and for good reason. Every Anubias variety attaches naturally to rocks and driftwood using its thick rhizome. In fact, Anubias should never be buried in substrate (burying the rhizome causes rot). We carry over 20 Anubias varieties, plus pre-attached options like Anubias on Lav
