Taxiphyllum 'Spiky' (Spiky moss)

11 November 2026

Spiky moss is an aquarium moss sold under the trade name Taxiphyllum 'Spiky'. Its strongly branched, three-dimensional shoots form dense green cushions or trailing growth on hardscape. The name is commonly used for a cultivated form, but it does not by itself establish a formally described species, so identification should remain conservative. It is generally adaptable and suitable for beginners when attached to wood or rock, provided circulation and regular trimming prevent debris from accumulating within the mat.

Identification

Taxiphyllum 'Spiky' is a trade or cultivar name applied to a moss with narrow, repeatedly branched shoots and a spiky, feathery appearance. The supplied name does not provide enough information to confirm a particular wild species, and aquarium mosses can be difficult to distinguish by appearance alone. It is therefore best recorded conservatively as Taxiphyllum 'Spiky' rather than assigned a more specific species name.

Placement and attachment

Use it primarily on driftwood, branches, stones, or other hardscape. Divide the material into small portions and secure them loosely with thread, fine mesh, or suitable aquarium-safe adhesive. Do not bury the moss in substrate; buried portions can decay. Keep the attachment layer thin so water can reach the lower shoots.

Lighting and carbon

Low to medium aquarium lighting is usually adequate. Stronger light can produce denser growth but also increases the risk of algae if nutrient and carbon availability are unstable. Carbon dioxide is not essential, although a consistent supply can improve growth and branching. Avoid sudden changes in lighting or carbon conditions.

Maintenance

Growth is slow to moderate under typical aquarium conditions. Trim with clean scissors when the cushion becomes too thick or begins to shade its lower layers. Remove loose fragments and siphon debris from the moss during water changes. Good circulation helps keep the branches clean and reduces the likelihood of stagnant areas and algae.

Propagation

Propagation is normally by division. Cut or separate healthy strands into small portions and attach them to new hardscape. New growth gradually anchors and spreads across the surface. Avoid taking excessively large clumps, which are more likely to trap detritus and detach from the hardscape.

Solenostoma tetragonum (Pearl Moss)

Medium

On rock or root

Solenostoma tetragonum is a small aquatic liverwort sold in the aquarium trade as Pearl Moss. The supplied product identification is consistent with the finely branched, bright green growth shown, although a definitive species determination cannot be made from product images alone. It is best used as an attached epiphyte on wood or stone, where its delicate texture provides detail without dominating the layout.
Phyllanthus fluitans (Red Root Floater)

Easy

Supporting plants

Phyllanthus fluitans is a free-floating South American aquatic plant with rounded, slightly swollen leaves and fine hanging roots. Under strong light, mature leaves may develop red or pink tones, while lower light generally produces greener growth. It is useful for absorbing nutrients, providing shade and offering cover near the surface. The supplied images show characteristic features, but coloration varies with light and growing conditions.
Schismatoglottis prietoi

Easy

Middleground

Schismatoglottis prietoi is a compact, green aroid with thick, gently wavy leaves and a clumping growth habit. It is suitable for the middle area of smaller or medium-sized aquariums, where its textured foliage provides contrast without dominating the layout. The supplied material supports identification as S. prietoi, although aquarium-trade plants can sometimes be confused with related Schismatoglottis species.
Sagittaria subulata (Needle Leaf)

Easy

Foreground

Sagittaria subulata is a grass-like, rosette-forming aquarium plant sold as Needle Leaf or Dwarf Sagittaria. Its narrow leaves arise from a basal crown and it spreads by runners, forming a low to medium-height patch when grown submerged. The exact form can vary considerably: some specimens remain compact, while others produce taller leaves under aquarium conditions. Identification is reasonably clear from the supplied label and plant appearance, but cultivar or commercial-form distinctions cannot be confirmed from images alone.
Rotala wallichii (Wallich's Rotala)

Advanced

Background

Rotala wallichii is a delicate, fine-leaved stem plant from Asia that can develop pink to red growth tips under strong light and stable carbon dioxide. The supplied source identifies the plant as this species, although a definitive identification from a photograph alone is limited. It is best suited to experienced aquarists and is commonly used as a detailed background or midground accent.
Rotala rotundifolia 'Blood Red' (Blood Red Rotala)

Medium

Background

Rotala rotundifolia 'Blood Red' is a red stem-plant selection of the highly variable Rotala rotundifolia complex. It forms dense, upright shoots with narrow leaves and can become intensely red under strong light, adequate carbon dioxide, and balanced fertilisation. The trade name identifies the aquarium form, but appearance can vary between cultivated lines, so exact clonal identity cannot be confirmed from images alone.
Sagittaria subulata (Dwarf Sagittaria)

Easy

Foreground

Sagittaria subulata is a grass-like, stolon-forming rosette plant commonly used to create a low, natural-looking foreground or transition. Its narrow leaves vary in height according to conditions and may become taller in deeper water or weaker light. It is generally adaptable and suitable for planted community aquariums. The supplied images are consistent with this identification, although aquarium-grown forms can vary in size and appearance.
Rotala rotundifolia 'H'ra' (H'ra Rotala)

Advanced

Background

Rotala rotundifolia 'H'ra' is a colorful stem-plant cultivar grown for its narrow leaves and warm orange, pink, or reddish tones under strong aquarium lighting. It is generally sold as a cultivated form of Rotala rotundifolia, although the exact lineage and selection history are not established here. With adequate carbon dioxide, nutrients, and regular trimming, it can form a dense background group. Color intensity varies with light, nutrient availability, and general aquarium conditions.
Riccardia chamedryfolia (Coral Moss)

Advanced

On rock or root

Riccardia chamedryfolia is a compact, branching liverwort commonly sold in aquascaping as coral moss or mini pellia. It forms dense, cushion-like green growth with a finely divided, coral-like texture. This identification follows the supplied source label, although commercial liverwort names can sometimes be applied inconsistently. It is best used attached to hardscape rather than planted deeply in substrate, where good water movement and stable conditions help maintain healthy growth.
Riccia fluitans (Pond liverwort)

Medium

Supporting plants

Riccia fluitans is a small, floating thalloid liverwort that can also be cultivated underwater as a bright green cushion. It has no true leaves, stems, or roots, and spreads by branching and fragmentation. Aquarium specimens need to be secured because they naturally rise to the surface. The supplied images appear to show several different moss-like plants, so identification is based primarily on the stated source name.
Ranunculus inundatus (River Buttercup)
