What Can You Grow in an In-Tank Aquarium Plant Basket?
By Nathan Trowbridge · Mossari
An in-tank plant basket supports a houseplant at the aquarium edge while its roots grow directly into freshwater. The leaves stay above the surface. The Mossari In-Tank Aquarium Plant Holder and Propagator offers room for lightweight supporting media such as LECA.

Which plants can grow with roots in aquarium water?
Pothos, Syngonium, and small Monstera adansonii plants are options listed for this basket. Lucky bamboo is another listed option; keep its foliage in air. Start with a clean, healthy, modestly sized plant or a stem cutting with the nodes it needs to root. A detached pothos or Monstera leaf without a node cannot become a complete vine.
These are houseplants grown with roots in water, not recommendations to submerge the whole plant. Success depends on light, nutrients, water conditions, and support. Move a plant to a larger setup before it overwhelms the basket.
Will the basket fit my aquarium?
The product specifies rimmed or rimless freshwater tanks with a mounting rim up to 7/8 inch thick. Measure the actual mounting location and account for lids, braces, and equipment. Tank volume alone does not tell you the rim’s thickness.
Do I need LECA in the basket?
LECA can help support roots and keep a small plant upright. The basket has a selectable LECA add-on. Rinse pellets outside the tank before adding them, and keep loose pieces from reaching equipment. The media supports the plant; it does not supply a complete nutrient diet.
Do not fill an open in-tank basket with ordinary potting soil or enriched wicking mix. Those belong in an appropriate planter chamber above the water. See Mossari LECA for the clay media option.
How do I start a plant in the basket?
- Choose an established freshwater aquarium with conditions suitable for its inhabitants.
- Prepare a plant with a known treatment history. Remove loose soil outside the tank; rinsing cannot guarantee removal of systemic pesticides. If uncertain, grow it separately first.
- Hang the basket securely and position the plant so its node or roots reach water while leaves and crown stay above it.
- Add suitable lightweight media if needed for support, without crushing the roots.
- Light the foliage and check root placement, stability, and water contact regularly.
Will it replace my aquarium filter?
No. Growing roots can use some dissolved nutrients, but uptake varies and a small new cutting has little root mass. Continue filtration, water testing, and appropriate water changes. Do not add ordinary houseplant fertilizer or rooting treatments to the aquarium.
Why are roots or stems turning mushy?
Remove deteriorating tissue promptly. Check whether leaves or vulnerable stem parts were submerged, whether the plant was healthy to begin with, and whether conditions suit it. Keep roots clear of intakes and remove dropped leaves before they decay.
Basket or Teardrop propagator: which should I choose?
The Teardrop Plant Propagator is a tidy starting point for a slender cutting. The basket offers a media-supported arrangement. Neither should be overloaded with a heavy mature plant.
Explore the in-tank basket and start with one manageable plant. Watching roots develop is part of the display.
