10 Aquaplants
found in the Philippines

A field guide to freshwater plants native to, or widely cultivated in, the Philippines — every entry checked for whether it's non-toxic and safe to keep with fish.

How "fish-safe" is judged here

All ten plants below are non-toxic freshwater aquatics with no documented reports of poisoning or harming aquarium fish or shrimp — they're regularly sold and kept in Philippine aquarium shops (e.g. Cartimar) and aquascaping farms. A few (Hydrilla, Water Hyacinth) grow aggressively in open waterways and are considered invasive weeds outside the tank — safe for fish, but keep contained in a home aquarium or pond.

The Plant List

10 species · native & naturalized

Palawan Sword

Cryptocoryne aponogetifolia

Native · Palawan

Long ribbon-like leaves that sway in current; one of the largest Cryptocoryne species and a Philippine aquarium-trade export.

Non-toxic, safe with all community fish & shrimp

Philippine Crypt

Cryptocoryne usteriana

Native · Philippines

A hardy, broad-leafed crypt endemic to Philippine streams; tolerant of varied water hardness once established.

Non-toxic; leaves are not palatable so fish leave it alone

Java Fern ("Philippine" var.)

Microsorum pteropus

Found · SE Asia incl. PH

Attaches to driftwood and rock instead of substrate; tough leathery leaves that most fish won't graze on.

Completely fish- & shrimp-safe, even with fin-nippers

Java Moss

Taxiphyllum sp.

Found · SE Asia incl. PH

A tangled carpet or wall of moss; a favorite spawning and hiding spot for fry, shrimp, and betta.

Non-toxic, actively protective for fry & shrimp

Anubias

Anubias barteri var. nana

Cultivated · widely in PH

Thick, dark-green leaves on a rhizome; grows on wood or rock and thrives in low light, even outcompeting algae.

Non-toxic; bitter sap deters grazing, so it's rarely eaten

Water Wisteria

Hygrophila difformis

Cultivated · PH aquarium trade

Fast-growing, lacy stem plant; excellent nitrate uptake makes it a natural water-quality booster.

Non-toxic and edible-safe if nibbled by herbivorous fish

Rotala

Rotala rotundifolia

Cultivated · PH aquascape farms

Slender stems that flush red under strong light, popular as a colorful background plant in local aquascapes.

Non-toxic; safe even in heavily-planted community tanks

Water Thyme

Hydrilla verticillata

Naturalized · PH waterwaysContain in tank

Whorled, fast-growing oxygenator found in rivers and irrigation canals across the country.

Fish-safe; grows aggressively so trim regularly

Dwarf Hairgrass

Eleocharis acicularis

Sold · PH pet & aquarium stores

Fine, grass-like carpeting plant used as a foreground lawn; a Cartimar aquarium-market staple.

Non-toxic; ideal for bottom-dwelling fish & shrimp

Water Hyacinth

Eichhornia crassipes

Naturalized · PH ponds & riversContain in tank

Floating rosette with inflated stalks and lavender flowers; trailing roots give fry a natural shelter.

Fish-safe; classified as an invasive weed in open water

"Fish-safe" reflects the consistent absence of toxicity reports across aquarium-keeping literature and the common horticultural/aquarium trade use of each species. This is a hobbyist reference, not a substitute for species-specific veterinary or ecological guidance — always research any plant before adding it to a tank with sensitive or specialty fish.

Here is an infographic highlighting three popular aquatic plants found in the Philippines, along with notes on their suitability for fish tanks.

Anubias Barteri (Anubias): Known for its large, hardy leaves, it provides excellent shelter for fish but is best attached to rocks or wood rather than buried completely in the substrate.
Cryptocoryne Wendtii (Crypts): These plants thrive in varying light conditions and create a dense, lush environment that many fish enjoy exploring.
Vallisneria Gigantea (Giant Vallisneria): Ideal for background placement, this fast-growing "grass" helps maintain water quality and offers protection for larger species.

As noted, all three are considered non-toxic and generally safe for most common aquarium fish

The local distinction matters: some plants are merely sold widely in Philippine aquarium shops, while a few are genuinely native. I’ll label those separately so the infographic doesn’t encourage collecting threatened wild plants.

Plant	Placement	Light	Helpful note
Anubias nana	Foreground/wood/rock	Low	Don’t bury its thick rhizome
Java fern	Wood or rock	Low	Hardy and slow-growing
Java moss	Wood, rocks or mesh	Low	Good shelter for shrimp and fry
Cryptocoryne wendtii	Midground	Low–medium	Root feeder; appreciates root tabs
Amazon sword	Background/centerpiece	Medium	Becomes large and needs nutrients
Vallisneria	Background	Low–medium	Produces runners and forms a curtain
Dwarf sagittaria	Foreground	Medium	Can create a short grassy carpet
Amazon frogbit	Floating	Low–medium	Provides shade; keep away from strong flow
