Want the look of moss without the maintenance? Subwassertang forms soft, translucent ruffled fronds that tangle into loose bushy clusters — and despite the name, it isn't a moss at all. It's the gametophyte stage of a fern, which is why it behaves so differently from anything else in the tank.
What You’ll Receive

Grower’s Notes
- It has no roots and no rhizoids that grip properly. Unlike Java Moss it won't fasten itself to wood quickly — tuck it into crevices, tie it under mesh, or glue it, and give it months to settle.
- It also works floating. A loose ball drifting at the surface is a legitimate way to keep it, and shrimp will graze it constantly either way.
- Keep it out of strong flow. The fronds are light and unanchored, so a powerful outflow will simply relocate your Subwassertang to the far end of the tank.
- It resists algae unusually well for a slow plant, which is why it holds up in long-term scapes where mosses eventually need stripping out.

Customers praised this vibrant moss for its "brilliant healthy green" color and generous portions. Praised for fast shipping and excellent packaging, most received healthy plants that fish and shrimp love. Some noted it arrives fragmented requiring tying to hardscape, and it's delicate—avoid harsh sanitizing. Overall highly recommended for quality and value.
- The Subwassertang was a brilliant healthy green and fair sized portion.
- This moss is sooo green and has stayed this hunter green. No browning.
- The subwassertang really makes the tank pop, pea puffers enjoy foraging through it.

A larger amount than I was expecting. Had very few melting pieces. A little hard to place when loose. I love the way it looks and my shrimp love it too.

I like the texture this moss has and so far it is growing. It came packaged nicely and in good health.

I’m very happy with my moss! It is absolutely beautiful and a good value for the amount you receive. My fish absolutely love it. Will definitely be ordering again, thank you!

I bought four packs and was slightly worried after some reviews. But what came was exactly as expected and I was able to form it into separate pieces and place where I wanted them to survive.
I expected a bit of loose debris and there was some but it isn’t too bad.
Hopefully it thrives in my tank and I’ll post another review.

The subwassertang really makes the tank pop, and the pea puffers enjoy foraging through it for their snails and worms

Plant received healthy. Very excited to have it continue to do so.

I’m anti-pest snail, and as such I use bleach to clean up hitch hikers. I know that susswassertang is a delicate plant, so I tried for a 30 second dip. Unfortunately, the vast majority of my susswassertang melted into nothingness, with a few shreds left here and there.
As far as the plants themselves, they arrived green and healthy, however they’re very messy, more like trimmings or pluckings than an individual plant. Definitely tie it loosely to some hardscape in a bunch and hope it doesn’t slip loose.
J
Came in good shape and very quickly. Really packed well. Will do business again
J
This moss is sooo green and has stayed this hunter green since I got it. No browning. On top of the color, it just looks so cool. My other moss has turned brown, not this.
H
Nice size portion, came is pretty good shape, good color. It was fragmented and scatter all over the tank along the bottom. I expected to be in clumps so that I could place it where I wanted. Wasn’t able to do that.
J
Tastes amazing and works perfect as a cappuccino garnish
C
Came in amazing condition, beautiful plants and one of my favorites with their semitransparent, cellophane like leaves. Gorgeous!!
J
Great looking when arrived
