Molly
Poecilia sphenops
Monte Carlo
Micranthemum tweediei
Monte carlo produces small, round leaves on creeping stems and is widely used as a foreground carpet alternative to hairgrass. It requires moderate to high light and CO2 injection to spread horizontally rather than growing upward. Its bright green colour adds a vivid pop to Nature Aquarium-style aquascapes.

Mosquito Fern
Azolla pinnata
Mosquito Fern is a small, floating aquatic fern with delicate, feathery fronds that form dense mats on the water surface. It displays distinctive reddish or brownish coloration under high light and nutrient-rich conditions. This fast-growing plant is excellent for shading and nutrient export, making it ideal for beginner aquarists.

Murdannia Keisak
Murdannia keisak
Pink-stemmed plant with narrow leaves. Develops beautiful pink-red colouration even under moderate light. Very easy red/pink stem plant.
Mushroom Coral
Actinodiscus spp.
Myriophyllum Aquaticum
Myriophyllum aquaticum
Parrot's Feather is a fast-growing, feathery stem plant with blue-green whorled leaves. It grows both submerged and emersed. Excellent for ponds and unheated tanks. Grows vigorously without CO2, absorbing nutrients rapidly and helping suppress algae. In warm tanks it may require pruning weekly to keep it manageable.
Myriophyllum Guyana
Myriophyllum sp. 'Guyana'
Very fine, feathery stem plant with orange-red tips under strong light. Creates a soft, cloud-like effect in backgrounds.
Myriophyllum Mattogrossense
Myriophyllum mattogrossense
Myriophyllum mattogrossense produces feathery red-green whorled leaves on reddish stems, creating an ornate background plant. Under high light and CO2 the foliage intensifies to deep burgundy. It is a fast grower that needs regular trimming.
Myriophyllum Tuberculatum
Myriophyllum tuberculatum
Red Foxtail is one of the deepest red aquatic plants available. It produces whorls of fine, needle-like leaves that range from orange-red to blood-red under intense light. The feathery texture combined with vivid colouration makes it a showpiece background plant in high-tech scapes. Demanding of light, CO2, and micronutrients.
Mystery Snail
Pomacea bridgesii
Mystery Wrasse
Pseudocheilinus ocellatus
Najas Guadalupensis
Najas guadalupensis
Known as Guppy Grass or Najas Grass, this fast-growing, fine-leaved plant is a superb filtration plant and spawning medium. It floats freely or can be weighted down. Its vigorous growth absorbs excess nutrients, helping combat algae. Very tolerant of a wide range of water conditions.
Narcissus Corydoras
Corydoras narcissus
Narrow Leaf Java Fern
Microsorum pteropus Narrow Leaf
Narrow Leaf Java Fern is a slender, elegant variant of the popular Java Fern with distinctly thin, needle-like fronds that create a delicate, feathery appearance. This slow-growing epiphytic fern thrives in low to medium light and requires no CO2, making it ideal for beginner aquarists. Its compact growth habit and attractive foliage make it perfect for attaching to rocks or driftwood in any freshwater setup.
Narrow Leaf Marsilea
Marsilea angustifolia
Low-growing fern that forms a carpet of narrow, single or double-lobed leaves. Very easy and adaptable foreground plant.
Narrow Leaf Sagittaria
Sagittaria subulata var. gracillima
Extra-narrow form of Dwarf Sagittaria. Grass-like appearance. Spreads quickly by runners. Great low-tech carpet/foreground option.
Narrowleaf Temple Plant
Hygrophila corymbosa
Narrow, willowy leaves give this variant a graceful, feathery appearance unlike its broad-leafed relatives. Great for creating visual contrast alongside wider-leaved plants. Just as hardy as the parent species.
Naso Tang
Naso lituratus
Nassarius Snail
Nassarius sp.
Nattereri Corydoras
Corydoras nattereri
Needle Hairgrass
Eleocharis acicularis
Eleocharis Acicularis, Needle Hairgrass, produces extremely fine, hair-like leaves that are noticeably thinner and longer than the closely related E. parvula, creating a delicate, windswept grass carpet effect. It requires good light and CO2 to spread vigorously via runners; without injection it grows slowly and sparsely. Regular trimming keeps the carpet dense and lush.
Needle Leaf Java Fern
Microsorum pteropus Needle Leaf
Needle Leaf Java Fern is a slender, delicate variant of the popular Java Fern with thin, needle-like leaves that create an elegant, feathery appearance. This rhizome-based epiphyte is extremely hardy and requires no substrate rooting, making it ideal for attaching to rocks or driftwood. It thrives in low to medium light and is one of the easiest aquatic plants for beginners.
Neomeris
Neomeris annulata
Tiny, elegant calcified algae with a barrel-shaped body ringed with white calcium bands at the tip. Short-lived (weeks to months) but reproduces readily in stable reef tanks. An interesting hitchhiker and occasional deliberate addition. Fish tend to leave it alone due to calcification.
