eSHa Ndx is an aquatic roundworm treatment that is levamisole-based. This can be used in freshwater and marine aquariums, and will work against many species of parasitic nematodes, including Camallanus, Capillaria, Pseudocapillaria, Eustrongylides, and Oxyuris.


  • 20ml bottle treats up to 454l for the recommended course, though longer treatments may be required
  • Suitable for all freshwater sytems, and fish only marine, though is not to be used with any invertebrates or corals
  • Effective against nematodes, including Camallanus, Capillaria, Pseudocapillaria, Eustrongylides, and Oxyuris.

    Ndx comes as a 20ml treatment bottle, and is not suitable for us with shrimp, crayfish or other invertebrates, and whilst it can be used on marine aquariums it should not be used with corals, anemones, urchins or other invertebrates. 

    Signs to look out for on your fish to see if they require this treatment include changing in skin colour or appearance, and clamped fins. Parasites can sometimes cause unusual swimming behaviours as well, and are sometimes visible to the naked eye. 

    What can I use with this treatment?

    Unlike most of the eSHa range, this should not be used in conjunction with any other treatment at the same time, though after treatment has finished it is actively recommended to also use a regular daily dose of eSHa Optima for good fish health too, acting as a great preventative for stress and disease. 

    How do I use this treatment?

    To use, start with your initial dose on day 1, using 100 drops per 100ml (100 drops is 4.4ml). On day 2, a 50% water change should be completed. In the case of some oviparous nematodes a repeated treatment may be required after 14 days to ensure that any recently hatched eggs are dealt with. As with most treatments, you should remove any chemical filtration that you have whilst you are treating the aquarium.

    Is this treatment suitable for my aquarium?

    This is suitable for use with freshwater systems, both tropical and coldwater, and can be used on marine fish in quarantine systems, though it could be harmful to marine invertebrates and corals.

    Pallet Drop Deliveries (Large/Fragile Items i.e. Fish Tanks)

    Large and fragile items such as fish tanks, which cannot be fulfilled by standard courier companies will be palletised and delivered within the pallet network. Pallet deliveries are undertaken by large vehicles where the pallet will be delivered curb-side for customers to process.

    Pallet deliveries are usually free of charge to mainland UK. Customers outside mainland UK will be contacted prior to processing your order should further charges apply.

    Due to the nature of the pallet network, expected delivery dates are only estimated. We endeavour to ask drivers to call customers in advance but this doesn't always happen. Should a delivery fall outside of your expected date, Complete Koi and Aquatics will not be liable for this. Once a palletised consignment has been despatched, it cannot be cancelled or refunded.

    Fish Deliveries

    ALL fish purchased via Complete Koi & Aquatics will also be sent out via APC as a next-day, non-conveyable, wet delivery with an AM time slot. Due to the health of the fish we are unable to offer an afternoon delivery. The fish are packed with plenty of oxygen and water to get them through the night. They are kept in the secure caged part of the vans and are handled with care. When the fish arrive, carefully float the bags in the pond to acclimatise them. Generally, we recommend floating the bags for around 30 minutes. After this we then recommend introducing small amounts of pond water to the bag for a further 15 minutes, prior to introducing them to their new home.

    Orders under £49.00 will also have the option to purchase our standard Royal Mail delivery service. This costs £3.99 and generally takes 2-3 working days.
