The Green Phantom Pleco is a beautiful addition to my aquarium. Its bright greenish-yellow color and flowing dorsal fin stand out. It’s very calm and doesn’t bother other fish. I’ve had it for three months and it’s thriving in a 20-gallon tank with driftwood and hiding spots.

This pleco is active and colorful. I noticed it spends time near the back of the tank, often near driftwood. It seems to enjoy the current and doesn’t eat much, which is fine. The fish looks healthy and is easy to maintain.

I was impressed by how peaceful this pleco is. It doesn’t chase or stress other fish, even with a school of tetras. The color is vivid and the fin movement is elegant. I recommend it for beginner to intermediate aquarists.
