Easy to set up and very active in the tank. It helps clean the glass and substrate. My tank looks cleaner after a few weeks. Only issue is it can get a bit territorial with other fish, so I keep it alone.

Great for a beginner aquarist. It stays calm most of the time and keeps the tank clean. I noticed it spends a lot of time on the glass, which is helpful. A little aggressive with a small tetra, so I moved it to a larger tank.

The pleco has been in my 20-gallon tank for three months. It’s very healthy and active. The water clarity has improved noticeably. I love how it doesn’t eat much and just cleans the tank naturally.

It’s okay, but it did show signs of aggression toward a small shrimp. I had to separate them. Still, it does clean the tank well and is easy to care for.
