Dojo loaches (weather loach) are legal to keep in UK home aquariums, but they grow up to 12 inches and need a large tank – at least 75 gallons for a small group. They are social, active fish that thrive in cool, well-oxygenated water.
What size tank do dojo loaches need?
Dojo loaches are active, bottom-dwelling fish that grow quickly. A single fish needs a 50-gallon tank, but they are social and should be kept in groups of three or more. Aim for a 75-gallon tank or larger. They prefer soft, sandy substrate to bury themselves and plenty of hiding spots.
Are dojo loaches illegal in the UK?
No, dojo loaches are not banned in the UK. Some loach species are restricted under the Invasive Alien Species regulations, but the weather loach (Misgurnus anguillicaudatus) is legal to keep, buy and sell. Always source your fish from a reputable dealer to ensure they are not wild-caught or from restricted areas. Check gov.uk for the latest on invasive species rules.
How big do dojo loaches get?
Dojo loaches reach 10 to 12 inches in a well-maintained aquarium. They grow steadily over two to three years. Their size means they outgrow small tanks, so plan for a large setup from the start.
What do dojo loaches eat?
They are omnivorous and accept sinking pellets, frozen bloodworms, brine shrimp and vegetable matter. Feed them a varied diet once or twice a day. They also scavenge for leftover food.
Can dojo loaches live with other fish?
Yes, they are peaceful but can be outcompeted by aggressive feeders. Good tankmates include danios, goldfish, and larger tetras. Avoid very small fish that might be eaten. Keep them in groups of three or more to reduce stress.
