Added this loach to my high-flow, cool tank after it had been running for six months. It quickly started grazing on the rocks and glass. Very active and peaceful. Only issue is males do get a bit territorial, so I kept five together and it worked well.

Great for a fast-moving tank. It clings to the rocks and keeps the surfaces clean. Feeding is simple with algae wafers and a bit of blanched zucchini. Needs a mature tank though, so not for beginners.

The blue tail is striking and it’s very hardworking. Keeps the tank clean and stays active even in strong currents. I’ve had it for three months and it’s thriving with no issues.
