Care
Many-flower ammannia (family Lythraceae) is an upright, branched herb up to about 60 cm tall, found in shallow water and damp heavy soils across Asia, tropical and subtropical Africa and Australia. It has narrow, stalkless, opposite leaves 0.5–5 cm long with heart-shaped bases and dense clusters of tiny flowers. In Victoria, Australia, it is called jerry-jerry and is considered vulnerable there. Wikipedia says nothing about aquarium use. Water figures are our estimate, not from the sources.

Breeding
From seed, or try stem cuttings.
Compatibility and tank mates
Soft stems are eaten by goldfish, large cichlids and herbivorous fish. Good with shrimp, snails and small community fish in tropical tanks.

Buyers are told to pay by PayPal Goods & Services, never PayPal Friends and Family, gift cards or crypto.
Live fish and other vertebrates must be sent by specialist live-animal couriers (for example APC Overnight or DX Express), never by Royal Mail. Some invertebrates and plants may go by Royal Mail Special Delivery or 1st Class within its rules.
Banned and invasive species (for example those on the GB invasive species lists) cannot be listed, and sellers must meet the site’s animal welfare standards.
