Low-light aquarium plants
Low-light plants thrive under standard aquarium LEDs or budget fluorescent tubes. They grow more slowly than high-tech alternatives but require less maintenance and are less likely to crash if something goes wrong with the lighting schedule. The slow growth of low-light plants also means less frequent trimming — useful in tanks where you want minimal intervention once established.
9 plants are flagged low-light — standard LEDs, not high-tech PAR fixtures.
How to read this list
Low-light means growth is slow, not optional light. A basic shop hood usually works; a dark room with a dead LED does not. Slow growers also give algae less competition for a while — keep nutrients and light hours under control until the plants fill in.
Anubias
Anubias barteri var. barteri
easylow lightNo CO2
Do not bury the rhizome, it will rot. Tie to wood or rock and allow roots to anchor naturally. Very low light suits it fine; algae on leaves is common in high-light tanks.
Anubias Nana
Anubias barteri var. nana
easylow lightNo CO2
Tie or superglue to hardscape; roots will grip the surface. Never bury the rhizome. Under very high light, algae may grow on the slow leaves, moderate light prevents this. Long-lived once established.
Cryptocoryne Wendtii
Cryptocoryne wendtii
easylow lightNo CO2
Expect melting leaves after purchase, do not uproot; wait for recovery. Root tabs help in inert substrate. Once established, it is very hardy. Spreads slowly to form a mid-tank cluster.
Duckweed
Lemna minor
easylow lightNo CO2
Good for tanks with goldfish or other herbivores that will eat it as food. Nearly impossible to fully eradicate, only introduce if you accept a permanent presence. Skimmer/overflow tanks spread it fast.
Hornwort
Ceratophyllum demersum
easylow lightNo CO2
Can be floated or loosely planted; will shed needles when conditions change. Trims frequently, cut the top growth and replant. Good for cycling tanks due to high nutrient uptake.
Hygrophila Polysperma
Hygrophila polysperma
easylow lightNo CO2
Almost impossible to kill. Trim frequently, it becomes a jungle fast. Plant cuttings directly in substrate. Good for giving a new tank a head start on nutrient cycling.
Java Fern
Microsorum pteropus
easylow lightNo CO2
Attach to driftwood with fishing line or plant-safe superglue; never bury the rhizome. Plantlets can be separated and reattached once they have a few roots.
Java Moss
Taxiphyllum barbieri
easylow lightNo CO2
Tie or superglue to surfaces; it will attach over a few weeks. No substrate needed. Trim occasionally to prevent it smothering other plants. Strong flow helps keep it clean.
Marimo Moss Ball
Aegagropila linnaei
easylow lightNo CO2
Keep cool: they prefer temperatures below 25°C and may brown and decompose in tropical tanks above 28°C. Roll them gently once a week to maintain their round shape. Rinse in dechlorinated water if they smell. Do not keep with strong plant-eating fish.
