Kiss nailed it. Common plecos, in my opinion, are great for ponds. Smaller plecs can be cool, but you generally pay a lot for them and seldomc get tot see them due to ther nocturnal natures. I say Ottos all the way. Oh, and sorry Petco messed you over, Sodee. It pays to check out selection, then research online, then go back to the store.Kissofthegorami said:A bristlenose or clown pleco would be fine. No one needs a comon pleco, they should stop selling them so frequently. Plecos do have their downside. They are messy and they all eat plants to different degrees. The bristlenose and clown pleco stay small but they will hide most of the time. true siamese algae eaters and otos are more fun to watch and are harmless to plants.
