The Green Phantom Pleco is a striking addition to my aquarium. Its bright green color with yellow spots stands out beautifully. It’s active and helps keep the glass clean by eating algae. I feed it a mix of sinking pellets and blanched vegetables every day. It’s peaceful with my other fish and has adapted well to the tank environment.

I bought this pleco for its unique appearance. It’s definitely eye-catching and does a good job cleaning algae from the tank walls. I noticed it gets slightly more active during the day. Feeding it a variety of foods keeps it healthy and happy. Just make sure to provide enough space since males can become territorial.
