The 9 Best Plants for Shrimp Tanks (and 3 You Should Skip)

Shrimp do not care about your aquascape. Your carefully arranged layout, your golden ratio hardscape, your immaculate plant trimming, the shrimp ignore all of it. What they care about is surface area. Every millimeter of plant surface grows biofilm, the invisible layer of bacteria, algae, and microorganisms that shrimp spend their entire lives grazing. More plant surface area means more food. More food means more shrimp. More shrimp means more baby shrimp. This is the entire equation.

The best shrimp plants maximize surface area, provide hiding spots for molting and juvenile shrimp, and tolerate the low-tech conditions that most shrimp keepers run. Here are the nine plants that deliver on all three, and three popular plants that create problems in shrimp tanks.

The Top 9

1. Java Moss (Taxiphyllum barbieri)

The undisputed champion of shrimp plants. Java moss offers more surface area per volume than any other aquarium plant. The tangled, fine-branched structure creates a three-dimensional grazing surface where shrimp pick through individual strands finding microorganisms. It also functions as the best nursery plant in the hobby, shrimplets hide in moss clumps from the day they hatch, grazing safely out of sight of any tankmates that might pick them off. Attach it to hardscape, let it float in a ball, or carpet the substrate with it. Java moss grows in virtually any conditions: low light, no CO2, room temperature. You cannot kill it.

2. Christmas Moss (Vesicularia montagnei)

Denser branching pattern than java moss with fronds that resemble tiny fir tree branches. Christmas moss grows flatter and more orderly, making it better for moss walls and hardscape attachment where you want a controlled, layered look. Shrimp love it equally, the branching structure provides the same biofilm surface area with a more attractive growth habit. Slightly slower growing than java moss, which means less trimming.

3. Subwassertang (Lomariopsis lineata)

Not actually a moss, it is a fern gametophyte that looks like tiny translucent green lettuce leaves. Subwassertang forms loose, tangled masses that shrimp absolutely devour in terms of grazing time. The rounded, flat fronds provide different surface textures than moss, hosting slightly different microorganism communities. Shrimp tanks with both moss and subwassertang offer dietary variety that supports healthier colonies. Growth is moderate in low light and it attaches weakly to surfaces, so most keepers let it free-float or wedge it between hardscape pieces.

4. Bucephalandra

The aquascaper's epiphyte that also happens to be excellent for shrimp. Buce grows attached to hardscape with thick, textured leaves that accumulate biofilm on their surfaces. The slow growth means each leaf persists for months, developing a mature biofilm layer that shrimp prefer over freshly grown surfaces. Smaller varieties like 'Wavy Green' and 'Kedagang' fit nano shrimp tanks perfectly. The one downside: buce is expensive. But a few pieces on your hardscape provide permanent, low-maintenance grazing stations that never need trimming.

5. Water Lettuce (Pistia stratiotes)

A floating plant with long, dangling roots that hang into the water column like a curtain. Shrimp climb the roots, literally ascending hand over hand, grazing biofilm along every root fiber. The roots also trap particulate matter that shrimp filter through. Above the surface, the rosette leaves shade the tank, reducing algae growth and making shrimp feel secure (they are more active and visible when overhead cover exists). Water lettuce grows fast, absorbs excess nutrients, and requires zero maintenance beyond occasional thinning.

6. Monte Carlo (Micranthemum tweediei)

A carpeting plant that forms a dense, low mat across the substrate. Shrimp graze the carpet surface constantly, and juvenile shrimp hide in the tiny gaps between stems at the substrate level. Monte Carlo tolerates low light better than most carpeting plants (though it carpets faster with CO2), making it viable in low-tech shrimp setups. The carpet creates a naturalistic ground cover that makes the entire substrate a feeding zone.

7. Pogostemon helferi ('Downoi')

Star-shaped rosettes with crinkled, zigzag leaf margins that create unusual texture at the foreground level. The textured leaves trap detritus and grow biofilm in every crevice. Shrimp pick through the leaf folds methodically, and the rosette shape provides shelter at the base where stems meet. Downoi needs moderate light and benefits from CO2 but survives without it in smaller, well-lit tanks. It adds visual interest that flat carpeting plants cannot match.

8. Java Fern (Microsorum pteropus)

Large, leathery leaves attached to hardscape via rhizome, same growth habit as Anubias. Java fern leaves develop brown spots on the undersides that produce tiny plantlets, and shrimp graze these spots aggressively. The broad leaf surfaces collect biofilm, and the spaces between fronds create shaded resting areas. Virtually indestructible in any light level. The 'Windelov' variety with branching leaf tips offers even more surface area for grazing.

9. Marimo Moss Balls (Aegagropila linnacea)

Dense, velvety algae spheres that shrimp treat like buffet tables. Shrimp perch on top, graze the surface, and roll the balls around the tank while feeding. Marimo grow in the coldest, lowest-light conditions imaginable. They require zero maintenance beyond occasional gentle squeezing during water changes to maintain their round shape. One or two marimo in a nano shrimp tank provide perpetual grazing enrichment.

3 Plants to Skip in Shrimp Tanks

Vallisneria

Val grows tall, fast, and sends runners everywhere. In a nano shrimp tank, it takes over within months, blocking light and crowding everything else. The smooth, ribbon-like leaves offer minimal surface area for biofilm compared to textured plants. It is not harmful, just inefficient use of tank space in small setups where every inch matters.

Hornwort

Hornwort is a superb nutrient absorber, but it sheds needle-like leaves constantly. The fallen needles decompose on the substrate, creating organic waste in a tank where you want pristine water quality. In large tanks this is negligible. In a 10-gallon shrimp tank, hornwort debris noticeably impacts water quality between maintenance sessions.

Dwarf Baby Tears (Hemianthus callitrichoides)

The most demanding carpeting plant in the hobby. HC requires high light, pressurized CO2, and rich substrate, conditions that create algae problems in shrimp tanks unless managed precisely. The CO2 injection required for HC growth can cause pH swings that stress Caridina shrimp. Unless you are an experienced planted tank keeper running a high-tech setup, HC creates more problems than it solves in a shrimp-focused tank.

Whatever you plant, know your water volume first. A 5-gallon nano and a 20-gallon long need very different planting densities to achieve the same coverage ratio. Use the tank size calculator to get your exact volume and plan your plant quantities accordingly.
