The Dojo Loach (Misgurnus anguillicaudatus) is an incredibly fascinating fish. These creatures are also known as Weather Loaches because their activity will increase significantly when the barometric pressure of the water changes. This means that, based on how active they are, they can act as a live weather predictor. This is what makes them incredibly popular among hobbyists.
Please Note: Dojo loaches are illegal to own and purchase in Illinois, Michigan, Minnesota and New York. Please be responsible and do not release any aquatic life into local waterways.
For whom is the Dojo Loach suited?
The Dojo Loach is an incredibly aquarium-friendly fish, making them pretty well-suited for beginner aquarium keepers, and their fascinating behavior is undoubtedly a reason to add them if you have space. You should note that a long aquarium is recommended due to the average adult becoming 25 cm long, and proper covering of their habitat is a must, as these fish are excellent jumpers!
What are they like?
These fish are very peaceful, allowing them to co-exist with a large variety of fish easily. They enjoy being in small groups and like burying themselves in the substrate of your aquarium, and will undoubtedly take any chance they get to explore every corner of their habitat, so make sure your filters are adequately covered! During the day, they are relatively inactive, but if they do noticeably get active, it's likely due to the increased barometric pressure.
The ideal conditions for the Dojo Loach
When it comes to the ideal conditions, the Dojo Loach is reasonably forgiving. They are fine in a temperature range of about 59 – 77 °F, and because they have evolved to survive harsh conditions, they are okay in most aquarium waters. However, just like with most other fish, they do require good filtration. As for the substrate, because the Dojo Loach likes to bury itself, sand or fine gravel would be optimal.
Our Tank Parameters:
This is such a cool fish. Glad we got one. It arrived healthy and active and much bigger than we were expecting. It does have one smaller fin just like Nemo but we have no way of knowing how that happened and it doesn’t seem to make a difference. The loach swims well and is much more active than we expected. Highly recommend this fish if you’re considering one, definitely do it!
Great customer service,
I hadn’t measured Do Jo in a few months and now he is 10 inches long and gorgeous! He gets along with community tank mates who are not aggressive toward him! The grandkids have enjoyed watching him over the years!!! Definitely one of the most interesting aquatic species! Love, love, love DoJo!!!!
My DoJo is 7 years old and 9 inches long! Over the years he has been the sweetest addition to our 20 gallon tank. I highly recommend getting one!
I’m really enjoying the dojo loaches. This is the one fish I would keep if I had to get rid of all but one. They are active and very personable.
