The Green Phantom Pleco is a beautiful addition to my 150-litre tank. It stays calm and actively grazes on algae, reducing the need for frequent cleaning. I love how it blends in with the green plants and driftwood. Very easy to care for.

It’s a peaceful fish that doesn’t bother other tank mates. I noticed it cleaning the glass and substrate regularly. The color is vibrant and it looks natural in the tank. Slightly shy at first but settles in quickly.

Great for beginners. I kept it alone and it adapted well. It doesn’t need much attention and helps keep the tank clean. The tank looks much more balanced now with the fish in it.
