Bought this Galaxy Pleco for my 55-gallon tank. It’s very calm and has been cleaning the substrate without any issues. The water parameters are stable and it seems happy in its environment. Great addition to a community tank with tetras and cichlids.

The pleco arrived healthy and has been active since setup. It doesn’t eat much but does keep the tank clean. I noticed it occasionally bumps into other fish, but nothing aggressive. Needs a bit of space though.

Perfect for a beginner aquarist. It’s peaceful, easy to care for, and helps maintain tank cleanliness. I’ve kept it for over a year and it’s still vibrant and active.
