Can someone please let me know what kind of Pleco this is?
Looks like a common pleco.
Yup common pleco, that particular one I have seen at 14-16 inches in length, so if you have anything under 125 gallons I would rehome it (they get about four inches from shoulder to shoulder across without counting for the fins, so you are looking at a bulldozer of a fish that will cause problems later, it needs a meatier diet and cannot survive off of algae alone).
It was from my uncle's tank. I am going to help him get his tank under control and properly stocked I think he is going to rehome it to someone with a pond
For the record, that is one of the best looking common pleco's I've seen. Great markings/
Separate names with a comma.
