Mosses
13 species profiled, Java and Christmas through Fissidens, Süßwassertang, Riccia and beyond. Attachment surface, typical use, trimming cadence, and the shapes each one forms underwater. The detail work that makes a scape feel alive.

Taxiphyllum barbieri
The default beginner moss. Tolerates almost anything but messy when left untrimmed. The shrimplet nursery of choice, dense fronds trap food and biofilm.
Vesicularia montagnei
Triangular 'christmas-tree' frond pattern is its signature. Needs slightly higher light than Java to keep that pattern; otherwise reverts to a stringy mess.
Taxiphyllum 'Flame'
Grows straight up in twisting columns, a distinctive look. Sensitive to high temperatures; struggles above 26 °C long-term.
Vesicularia ferriei
Grows downward, perfect for the 'weeping willow' tree look on tall driftwood. Needs steady CO₂ and decent flow to weep properly without trapping detritus.
Taxiphyllum sp. 'Peacock'
Feathery, slightly iridescent green. Slower than Java/Christmas, patient growers are rewarded with one of the most ornamental mosses available.
Taxiphyllum sp. 'Spiky'
Taller, more pointed fronds than Christmas moss, bushier overall look. A great all-rounder when you want a textured moss surface without weeping.
Vesicularia sp.
A more compact Christmas moss with smaller fronds, best moss for nano bonsai trees and miniature aquascapes. Slow but worth the wait.
Riccia fluitans
Amano popularised it as a substrate carpet, but it has no roots, so it must be tied under stainless mesh. Pearls oxygen aggressively under CO₂ and high light.
Fissidens fontanus
A premium feature moss, small, fern-like fronds that hug stone. Slow growth means it stays compact and ornamental for months between trims.
Lomariopsis lineata
Technically the gametophyte stage of an aquatic fern, not a true moss. Forms dark green ruffled mats. Hardy and undemanding, a stealth favourite among aquascapers.
Vesicularia dubyana
The historically 'true' Java moss — what was originally sold under that name before Taxiphyllum barbieri displaced it. Frond pattern is more irregular and shaggier than modern Java moss, with a deeper green colour. Slightly fussier on water quality and needs better light to keep dense.
Leptodictyum riparium
Long, thin, string-like fronds that drape from hardscape like underwater Spanish moss. Prefers cooler water than most aquarium mosses — pairs well with white cloud minnows, hillstream loaches, and other subtropical species. Will brown in tanks held above 26 °C long-term.
Monosolenium tenerum
A thalloid liverwort, often confused with mosses, with flat ribbon-like fronds that grow in tight clumps. Heavier than most mosses, which lets it anchor itself on flat stones without thread. Pairs visually with iwagumi-style hardscape; offers a contrast texture to the fibrous look of Java or Christmas moss.
