How to keep dojo loaches

Dojo loaches are long, playful cold-water loaches that burrow in sand and get restless before storms. A group in a 55 gallon or larger covered tank suits them, including goldfish tanks. They are invasive in parts of the United States; never release one.

Diet: Omnivore: sinking pellets, frozen foods, worms. Fish food types compared · how often to feed.

Where they swim: Bottom of the tank.

Dojo loach tank mates

Common dojo loach problems

Test the water first whenever fish look unwell: see what your readings mean, then match the symptom. For disease, a vet who treats fish can diagnose it and advise treatment.
