Hello, I have a 20g long that is going to have 4 male Honey Gouramis in it. I'm curious which species of Cory would be best for the tank with this stocking. Panda Corys or Pygmy Corys? I'd like to do a group of 16. I'm leaning towards Pygmy Corys, but I love the appearance of Panda Corys, so please let me know. Thanks for the help!
