Panda cories do seem a bit more delicate than some of the other cory species. I bought a trio last year and was intending to get another trio so I had six, but I lost two during the first week so decided against getting any more. The lone panda is now shoaling with my six Adolfoi, though I still wonder whether he'd be happier with his own kind...
Maybe I'll risk trying some more at some point; I have all my cories in a different tank with a sand suibstrate now, they might do better.
