Aquatic Plants

Subwassertang

A unique aquatic plant with flat, rounded overlapping lobes unlike any moss or fern in the catalog -- producing exceptionally dense interior biofilm and providing shrimplet cover that no other plant structure matches.

Flat Rounded Lobes -- Unique Structure Densest Interior Biofilm of Any Plant Exceptional Shrimplet Cover Floats or Anchors Loosely No CO2 Required Low to Medium Light

Subwassertang (commonly attributed to Lomariopsis lineata, though the exact taxonomy remains discussed in the hobby) is a freshwater aquatic plant with a growth form unlike anything else in the catalog -- flat, broadly rounded lobes that overlap in an irregular, loosely branching mass resembling a miniature liverwort or flattened fern in a way that is clearly distinct from needle-like moss fronds, divided fern leaves, or any stem plant structure. It is the most unusual-looking plant in the shrimp tank catalog and also one of the most practically valuable: the overlapping lobe structure creates sheltered micro-environments between surfaces where biofilm accumulates at a density and diversity that flat-surface plants cannot match, and the enclosed interior spaces of a developed Subwassertang mass are large enough for adult shrimp to navigate through but fine enough to provide complete physical concealment for shrimplets within the first days of their lives. It can be floated at the surface, weighted at mid-depth, or pressed against hardscape where it anchors slowly over several weeks. Fully safe with all Neocaridina, Caridina, and snails.

What to Expect

Structure, Biofilm and Growth

Flat rounded lobes in an overlapping irregular mass -- unlike any other aquatic plant -- each Subwassertang frond is a flat, broadly rounded lobe -- smooth-edged and clearly rounded rather than pointed, needle-like, or divided. The lobes grow in overlapping layers from branching points, building a mass that is visually unlike any moss, fern, or stem plant and that is immediately recognisable at a glance as something outside the usual planted tank plant vocabulary. The visual interest of Subwassertang as a planted tank element is as much in its unusual structure as in its function. The densest interior biofilm of any plant in the catalog -- the sheltered micro-environments between the overlapping lobe surfaces accumulate biofilm at a density that exceeds what exposed flat plant surfaces can produce. Shrimp work continuously between the lobe layers, disappearing into the mass for extended foraging sessions. Shrimplets in particular spend large portions of their first weeks inside the interior of a Subwassertang mass, where biofilm density is highest and physical concealment is most complete. Exceptional shrimplet shelter -- interior spaces are sized for the youngest juveniles -- the gaps between overlapping lobes in a developed Subwassertang mass are large enough for shrimplets to navigate but small enough to provide genuine physical concealment from the open tank. A newly released shrimplet entering a Subwassertang mass disappears from view almost immediately -- the mass provides the most complete concealment structure available in the catalog for animals at the scale of newly released Neocaridina and Caridina juveniles. Floats, anchors at mid-depth, or attaches loosely to hardscape -- flexible placement -- Subwassertang does not produce firm rhizoid attachment structures like moss and anchors to hardscape only loosely and slowly over several weeks. It is most practically used as a floating mass at the surface, weighted loosely to mid-depth with a small stone or plant weight, or pressed against a hardscape surface and held in place initially with cotton thread until partial attachment develops. Grows more slowly than Java Moss -- patience for full mass development -- Subwassertang grows at a measured pace, adding new lobes from growing tips over weeks rather than spreading visibly week to week. A newly introduced portion takes three to five weeks to begin clearly expanding before entering a steadier growth phase. The slow initial pace is normal and expected.
How to Set It Up

Getting Started

1Float at surface or weight loosely to mid-depth for easiest initial placement -- floating Subwassertang at the surface where it forms a spreading mat is the simplest introduction method requiring no attachment work. Alternatively, attach a small plant weight to a portion of the mass and lower it to mid-depth where it provides a floating mid-water shelter structure.
2For hardscape attachment, secure with cotton thread and allow three to six weeks -- press the mass against the target hardscape surface and wrap loosely with cotton thread to maintain contact. Partial attachment develops over three to six weeks -- significantly slower than Java Moss. Leave undisturbed during this period.
3Low to medium light -- excess light encourages algae inside the dense lobe structure -- algae establishing between the overlapping lobes of Subwassertang is difficult to remove once present. Consistent low to medium light prevents algae establishment while supporting steady lobe development.
4Fertilise lightly and consistently -- balanced liquid fertiliser two to three times weekly. Subwassertang is not a heavy feeder but consistent low-level nutrition produces more even lobe development than intermittent fertilisation.
Bonus Tip

A floating mass of Subwassertang in a breeding tank or shrimplet rearing setup -- left to form a spreading surface mat at the water interface -- creates the most productive combination of surface shelter, mid-water concealment, and biofilm food source achievable with a single plant. Newly released shrimplets rise into the underside of the floating mat and immediately have access to the richest biofilm surface in the tank combined with complete concealment from the open water below. In a dedicated breeding setup, a Subwassertang mat at the surface alongside Cholla Wood on the substrate provides complete coverage of the vertical range from substrate to surface with complementary shelter structures at every level.

Policies & Disclaimers

Choosing your portions, using the plant promotion, and knowing what to expect when your plants arrive.

Buy 2 Get 1 Free: add all three

Choose three eligible plant items and add all three to your cart, including the plant you want free. The discount applies automatically at checkout; no code is needed. Adding only two items does not add a third plant for you.

Mix and match eligible varieties or choose multiple quantities of the same eligible plant. The least expensive eligible item is free. For example, with eligible items priced at $5, $8 and $10, the $5 item is discounted and the plant subtotal is $18 before shipping and tax.

The offer repeats for complete qualifying groups: three eligible items give one free, six give two free, and nine give three free. The current offer has no per-order use limit. Items must be included in the promotion; Plant Weights and other non-plant accessories do not qualify.

An item means the sale unit in your cart. One bunch, cup, portion or multipack counts as one item when purchased at quantity one, not one item for every stem, leaf or bulb inside it. Check the listing and selected option for what each unit contains.

Check the discount and quantities in your order summary before paying. Other promotions can affect the final discount; multiple product discounts do not stack on the same item. This is an online checkout offer, not an automatic in-store POS discount.

Plant Promotion Details

Portions, sizes & what you receive

Read this plant’s description and selected option for its sale format, portion size and any stated stem or plant count. A bunch, loose portion, rooted plant, bulb, cup and mounted plant are different products; there is no single size or count that applies to every plant we sell.

A mature height or spread describes potential growth in an aquarium, not the size shipped. Use the advertised purchase portion to plan your order. A full carpet, dense moss-covered surface or established group in a photograph may require several portions and time to grow.

Do not assume that a pot, planting weight, rock, wood, substrate or other display accessory is included unless the listing explicitly says it is. If the received portion appears different from the selected listing, photograph it with its packaging and contact us promptly.

Photos, color & natural variation

Photos illustrate the named plant or variety and its appearance. Living plants vary in leaf size, shape, root development, branching and fullness; a photo of an established specimen is not a measurement of each portion shipped. The product description and selected option remain the reference for your purchase.

Aquarium lighting, camera settings and the growing environment affect perceived color. Red or pink varieties can look different under different lighting and growing conditions. Do not use a photograph alone to select a plant’s care requirements or expect immediate mature coloration.

Above-water growth & the transition underwater

Some aquarium plants can grow with their leaves above water as well as submerged. These growth forms can have different leaf shapes and appearances. New underwater growth may look different from older leaves as the plant adjusts. This explanation does not mean every plant is supplied in the same growth form; follow any specific information in the listing.

Leaf loss or softening after a change of environment is often called melt. Look at the plant as a whole and its growing points rather than judging only one older leaf. Do not assume that a damaged plant is simply transitioning or wait for new growth before reporting an arrival problem.

This is background care information, not a new exclusion from the Live Arrival Guarantee. Arrival damage is assessed under the existing policy.

Planting: match the method to the plant

For stem plants, separate the stems and plant with room between them. For rosette plants, position the roots in the substrate without burying the crown. Remove transport bindings and growing material carefully where appropriate.

For Anubias and Java fern, keep the rhizome exposed rather than burying it. Moss can be divided into smaller portions and attached to suitable hardscape. Floating plants belong at the surface. Bulbs and tubers need species-specific planting depth; do not assume every type should be fully buried.

Keep plants damp while working. Follow the individual listing for placement and care, especially when a plant has unusual requirements. These are planting tips, not additional conditions for a claim.

Growth, tank conditions & choosing companions

Plan for the plant’s mature size, available light and the space it will occupy. A background stem plant, slow-growing rhizome plant and floating plant serve different roles; a purchase portion does not instantly create a finished aquascape.

Use the listing’s guidance on light, nutrients and carbon dioxide rather than assuming every plant needs the same setup. Growth rate and final appearance depend on aquarium conditions and maintenance. More light alone is not a substitute for a balanced setup.

Consider animals that dig, uproot or eat plants before choosing placement. Floating growth can shade plants below it, and fast-growing plants may need thinning. Observe new growth and make gradual, species-appropriate adjustments.

Hitchhikers & introducing plants

Our existing policy does not guarantee pest-free arrival. Plants can carry tiny organisms or eggs, including snail eggs, despite inspection. Inspect new plants before introduction, and consider separate observation or quarantine to protect an established aquarium.

Do not assume a plant is sterile, pesticide-free or safe for a particular treatment unless the listing explicitly provides that information. Sensitive leaves, mosses and roots can respond differently to dips. Research the exact plant and any treatment before using it; do not apply an animal medication or a strong dip by default.

Arrival problems: document and contact us promptly

For damaged or dead plants, email support@superiorshrimpaquatics.com within two hours of the carrier’s recorded delivery time. Use the email address on the order and include all arrival concerns in your first message.

Send clear photographs of the affected plants and their packaging, with the shipping label or invoice visible for identification. Photograph packaging damage before unpacking or discarding materials, and consult the full guarantee’s documentation instructions. Keep the original photos.

The current guarantee covers aquatic plants but excludes promotional or free items. That existing exclusion also matters when ordering a free promotional plant. Claims and available resolutions are assessed under the full policy; this tab does not expand or reduce coverage.

Live Arrival Guarantee
