Can Dojo Loach Live With Rosy Barb?
Yes, dojo loaches and rosy barbs coexist well in 40 gallons or larger because both species prefer cooler water and occupy different levels of the tank.
Why
- Dojo loaches are bottom-dwelling fish that search the substrate for food, while rosy barbs swim in the middle and upper levels.
- Both species tolerate the same cooler temperature range of 64-72°F, which is lower than typical tropical tanks.
- pH overlap of 6.5-8 covers a wide range from slightly acidic to alkaline water.
- Rosy barbs are peaceful schooling fish that do not bother slow-moving bottom dwellers.
- Dojo loaches are hardy and tolerate the active swimming patterns of a barb school without stress.
What could go wrong
Dojo loaches are slow swimmers and may miss out on food if rosy barbs are too enthusiastic at feeding time. Target feeding helps prevent this.
