I have a school of 4 Albino Cories and 1 Emerald Green Cory and they seem very active and happy. There are plenty of places for them to hide, but they dont seem to hide as much as the ones Ive had in the past. They are all small, but growing. As for the Peppered or Panda, I like the Peppered more, but I like all the species of Cories. There arent very many panda cories in the LFS's around here, they keep mostly the albinos and emerald green cories..
