A waterweed in Wikipedia's list of freshwater aquarium plants. None of our three sources had a page for it, so its origin, size and needs are not confirmed and this page is short. Other Elodea species are fast-growing, submerged stem plants with whorls of small leaves, planted in bunches or left floating, and they need little special care. Expect similar treatment to suit it, but check its origin before choosing coldwater or tropical temperatures. Never release this plant or dispose of it in drains or waterways; it is invasive in some countries. Sources: Wikipedia, List of freshwater aquarium plant species. Checked October 2026.
Breeding
Elodea species are propagated by cuttings: plant stem pieces in the substrate or let them float until they root.
Compatibility and tank mates
Elodea species are soft plants that goldfish, large cichlids and plant-eating snails will eat. They give good cover for fry and shrimp.

Items are sold by auction, buy it now or classified advert, by hobbyist and business sellers in the UK.
Buyers pay sellers directly; Aquatic-Auctions does not hold the money. Hobbyist sellers must offer PayPal and may also take cash on collection. Business sellers take PayPal (required) or cash on collection, and bank transfer only once they have a seller rating of 50 out of 100, a company and pet-selling licence checked by Aquatic-Auctions, a bank account in the company's name, and bank details approved by Aquatic-Auctions.
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.
Members must be 16 or over to buy (16 and 17-year-olds with a parent or guardian’s agreement); sellers must be 18 or over.
Business sellers show their address, company details and pet-selling licence to buyers. Seller ratings run from 0 to 100: +1 for each positive feedback, −1 for each negative.
