If you keep dojo loaches (weather loaches), watch for increased activity ahead of rain – these fish are sensitive to falling barometric pressure. Provide a minimum 120-litre tank, smooth substrate, and cool, well-oxygenated water to keep them healthy.
What tank size and conditions do dojo loaches need?
Dojo loaches reach 20–25 cm (8–10 inches) in length, so a tank of at least 120 cm long and 120 litres capacity is recommended. They prefer temperatures between 10 and 24°C, making them suitable for unheated indoor tanks in the UK climate. Soft, sandy substrate protects their sensitive barbels; strong filtration and regular water changes are essential. They are social fish – keep groups of three or more to reduce stress. For outdoor ponds, ensure the water does not freeze solid; dojo loaches can tolerate winter cold but need a deep, unfrozen zone. Monitor barometric shifts using our 10-day weather forecast to predict behaviour changes.
Are dojo loaches illegal in the UK?
Dojo loaches (Misgurnus anguillicaudatus) are legal to keep in private aquariums in the UK. However, they are listed under Schedule 9 of the Wildlife and Countryside Act 1981 as an invasive non-native species – it is illegal to release or allow them to escape into the wild. Always source your fish from reputable UK retailers and avoid unverified online sellers. For local weather patterns that may affect outdoor ponds, check the UK weather hub.
Are dojo loaches banned in the UK?
No, dojo loaches are not banned for private keeping. They are classed as invasive under Schedule 9, so releasing them into the wild is illegal. Keep them securely in a tank or pond.
How big do dojo loaches get?
Dojo loaches typically grow to 20–25 cm (8–10 inches) in optimal conditions. Their size requires a spacious tank of at least 120 litres and 120 cm length.
What do dojo loaches eat?
They are omnivorous bottom-feeders. Offer sinking pellets, frozen bloodworms, brine shrimp, and blanched vegetables like zucchini. Feed once or twice daily, only what they can eat in two minutes.
