The flagtail cory is a beautiful addition to my aquarium. Its distinct tail pattern stands out and it’s very active without being aggressive. I feed it a mix of sinking pellets and algae wafers, and it enjoys the bottom feeding.

I’ve had this cory for six months and it’s still healthy and active. The gold highlights on its fins are especially nice. It does best in a well-maintained tank with stable water parameters.
