Dojo Loach
The dojo loach is also called the weather loach because it tends to get more active when bad weather approaches. In fact, this aquarium fish has been used for centuries to predict coming storms. Dojo loaches need clean water and room to swim. Dojo loaches are friendly, tolerate colder water temperatures and will eat most foods.
A few states will not allow gold or regular dojos: New York, Illinois, Michigan, Minnesota and Alabama.

I’ve had my dojo loach for three months now and it’s very active, especially during rainy days. It’s peaceful and eats most of the food I offer. The water quality stays stable, and it’s a fun addition to my tank.

The fish is calm and doesn’t stress other tank mates. It shows signs of activity before storms, which is a cool feature. I keep it in a 10-gallon tank with a heater, and it thrives in cooler conditions.
