Plant information
Monosolenium Tenerum
About this plant
Thicker than moss, and that is the point. Monosolenium tenerum — Pellia — is a liverwort that grows broad ribbon-like fronds rather than fine filaments, forming dense dark green cushions with real substance. It gives a texture nothing else in a planted tank offers, and it does it in low light with no CO₂.
What you'll receive
- Loose Portion: small portion of Monosolenium tenerum, approx. 2" x 2" (5 cm x 5 cm)

- Photos shown are sample representations. Actual plant portions may vary in size and density. Unless noted, plants may arrive in emersed or submerged form and are not guaranteed to be pest- or pesticide-free.
- Never release aquarium plants into natural waterways.

Grower's notes
- It has no roots and no grip — you must tie it down. Unlike Java Moss, Pellia is brittle and heavy and will not attach itself. Use thread, hairnet or mesh over rock, and expect to leave it several months before it holds. Dropped loose on the substrate it simply drifts apart.
- Keep the light modest. Slow growth means algae settles faster than the plant replaces tissue, and algae inside a dense Pellia cushion cannot be cleaned out.
- Give it flow. Water moving through the cushion keeps detritus from packing into the center and rotting.
- Split and re-tie rather than trimming. Fragments grow into new cushions, so one portion becomes several over a year.
- Shrimp and fry take shelter in it readily — the dense structure is better cover than fine mosses provide.

How it arrives
A sealed Vitro Culture® bag
Lab-grown plantlets in nutrient gel, free of snails, algae and pests.
- Keep it sealed at room temperature, out of direct sun, until you're ready to plant.
- Rinse off all the gel under lukewarm water. Left in the tank, it clouds the water and feeds algae.
- Split into small portions and plant with tweezers. Small portions spread faster than one big clump.
Normal: a little melt in the first weeks as underwater leaves replace the leaves grown in the lab.
Rooted plants in a net pot with rockwool
The most stable option, with roots already established.
- Rinse the plant under clean water.
- Plant the pot as is, or ease the plant out and gently tease away the rockwool. Either way works.
- For epiphytes like Anubias and Bucephalandra, keep the rhizome above the substrate or tie it to wood or rock.
Fresh-cut stems in a net pot with rockwool
Freshly cut stems without roots, held upright in a net pot for a quick setup.
- Rinse the stems under clean water.
- Plant the pot as is, or remove the stems and plant them one by one, an inch or two deep.
- New roots usually form within a couple of weeks.
Rooted plants bundled with foam and a plant weight
Easy placement plus the stability of roots.
- Rinse the bunch under clean water.
- Place the bunch as is, or remove the foam and weight and plant each one separately.
- Give each plant room so light reaches the lower leaves.
Fresh-cut stems bundled with foam and a plant weight
Freshly cut stems without roots, ready to drop in.
- Rinse the stems under clean water.
- Remove the foam and weight and plant stems one by one, an inch or two deep, for the fullest look. You can also place the bunch as is.
- New roots usually form within a couple of weeks.
Loose, rooted plants
No pot or foam, so you can place them exactly where you want.
- Rinse the plants under clean water.
- Plant the roots into the substrate, or tie the rhizome to wood or rock with cotton thread (never glue). Don't bury the rhizome.
- Trim any broken leaves; new growth follows once settled.
Loose, fresh-cut stems
Freshly cut stems without roots, for full flexibility.
- Rinse the stems under clean water.
- Plant stems one by one, an inch or two deep, with a little space between them.
- New roots usually form within a couple of weeks.
A bulb, ready to sprout
Bulbs ship either dormant or already sprouted with leaves, depending on the option you choose.
- Rinse the bulb under clean water.
- Rest it on the substrate or press the base in slightly. Don't bury the top.
- A dormant bulb can take a few weeks to send up its first leaves.
A young sprouted tuber
Ready to pot up and grow into a full plant.
- Pot it in a wide container of heavy garden soil, crown just above the soil.
- Start shallow and lower it deeper as the leaves grow.
- Give it full sun once the leaves reach the surface.
Attached to hardscape
Already growing on rock or wood, so it's ready to place.
- Rinse the piece under clean water.
- Place it anywhere in your layout. No planting needed.
- Keep the rhizome out of the substrate.
Packed fresh to travel well
- Open the box as soon as it arrives.
- Rinse the plants under clean water.
- Plant or place them the same day if you can.

Are your plants free from pests, algae, and pesticides?
Our plants are very clean, but we can’t guarantee they will be 100% free of hitchhikers (snails, algae, pests), because we can’t be responsible for your aquarium. We recommend rinsing all plants with clean water and quarantining them before use.
Plants in our Tissue Culture collection are 100% free of pests and algae and have never been in contact with any aquarium.
We don’t guarantee our plants are free of pesticides. We use homemade, organic pesticides in our greenhouse to control pests, and never pesticides containing copper, which is toxic to invertebrates such as snails, crabs, and shrimp.
We don’t guarantee your aquarium’s success and aren’t responsible for its inhabitants, including but not limited to fish, shrimp, snails, and turtles. Please quarantine all plants before use!
Are your plants grown emersed or submerged?
It depends on the species. Most of our plants are grown hydroponically in a controlled-environment greenhouse.
Common stem plants such as Ludwigia, Bacopa, and Myriophyllum, and rheophyte/epiphyte plants (Anubias, Bucephalandra, Microsorum, Bolbitis, etc.) are grown emersed, hydroponically, in a controlled high-humidity environment.
True aquatic plants that can’t grow emersed — such as Vallisneria, Elodea, Najas, Cabomba, Potamogeton gayi, and Ceratophyllum demersum — are always cultivated submerged, underwater.
Should I remove the foam, weight, or pot before planting?
It’s totally up to you — we usually keep them as they are!
What’s the difference between fresh-cut, bare-root, and potted plants?
All options offer the same high quality; they differ in how they are prepared and packaged:
- Fresh-cut Plants: loose, freshly cut plants without roots. Great flexibility if you prefer to plant them your own way.
- Fresh-cut Bunched: freshly cut plants without roots, bundled with foam and a plant weight, ready to place in your aquarium.
- Fresh-cut Potted: freshly cut plants without roots, potted in a net pot with rockwool for stability and a quick setup.
- Bare-root Plants: loose, rooted plants you can position exactly where you want.
- Rooted Bunched: rooted plants bundled with foam and a plant weight — easy placement plus the stability of roots.
- Rooted Potted: rooted plants potted in a net pot with rockwool — maximum stability and a low-maintenance setup.
Choose based on your planting preference and your aquarium setup.

This aquatic moss generally arrives quickly and healthy, with customers praising its "lush green" appearance and pest-free quality. However, some shoppers received degraded, brown material instead of the expected clumps. Most appreciated the generous portions and ease of growth, though consistency varies.
- It arrived healthy, lush green, and with no hitchhikers!
- These are gorgeous plants, they look like seaweed and are very easy.
- Very cool plant. Arrived quickly in excellent condition.
While all the other plants in the order arrived healthy and in good shape. This mono specimen arrived very degraded and brown “dead”. it looked like it had been kept in the bag for a week and/or was the very bottom of the barrel. The package contained very few pieces of green “live” plant material. This may be enough to regenerate over the next couple of months, but very disappointing. The photos are of what is left after pulling out the majority of dead material. Also noticed some hitchhikers. Snails, snails. Everything in the aquarium is from the same order.
I expected mine to come in one big clump like in the picture, but it came in mini small little fibers that have now died Do not recommend this is a product to buy from here specifically. Maybe when it’s not on sale because they’ll give you an actual good product. Because I did buy it on sale and maybe that’s why I got what I got. Here’s a picture of what I can find that is still. Slowly dying in my tank. If any of this actually does survive, I will be surprised.
Plants arrived quickly and in great shape! Most plants didn’t melt at all, some wear on the moss but it looks healthy. Thank you!
It arrived healthy, lush green, and with no hitchhikers, which I appreciate greatly!
I have received parasites, scuds, and leaches in some plants from other sellers, BUT not from here. They do not have any duck weed either, which is almost impossible possible to remove, it always seems to pop up. Just order you don’t have to worry like you do other places.
These are gorgeous plants, they look like seaweed to me and can grow anywhere, they are very easy,
Very cool plant. I was provided a generous portion that arrived quickly and in excellent condition. It looks amazing attached to the dragon-stone in my aquarium.
I believe these came with snails which was just what I wanted and are looking great in my 10 gallon tank
