I ordered size large so they would match the one Pajama Cardinal I had and they were bigger than I expected. Arrived healthy and ready for the tank.

Cardinals are probably the most peaceful fish out there. I was very surprised when I received this one. He was the biggest cardinal I have ever seen. He was the largest fish in the tank that housed him. Bigger and still friendly. Good thing about when they are larger, they don’t get picked on.
