Care
Najas indica is an Asian water nymph found from the Indian subcontinent to China, South-East Asia and New Guinea. Najas (water nymphs or naiads) are slender, brittle, fully submerged plants with narrow, finely toothed leaves, found almost worldwide. Our sources give no more about this species. Grow it like guppy grass: planted loosely or floating as soft, fast-growing cover in tropical tanks. Water figures are our estimate, not from the sources. Sources: Wikipedia (en.wikipedia.org/wiki/Najas); Wikipedia, List of freshwater aquarium plant species. Checked October 2026.
Breeding
Broken stem pieces grow into new plants.
Compatibility and tank mates
Fine-leaved stems trap debris and are grazed by goldfish, silver dollars and large cichlids. Shrimp, fry and small tetras and rasboras suit it well; avoid strong flow and heavy diggers.

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.
