Cory Problem

[KrystaK]

I have a 30 gal tank (36x12x18)
Temp is 76 and as of yesterday the readings were all normal..the pH was 8.0 (Which is normal for my tank)

I have two Mollies, two Platys and my Panda Cory. I know it's not an ideal set up but they're the survivors of a stressful tank change (My old 30 g developed a leak during a house renovation and no one noticed until it was almost to late...)
So it's been about 4 days now and the Cory seems to be struggling, he's breathing rapidly and almost looks like he's clinging to the bottom and I've fed them and normally he freaks out happy but now he's completely ignoring the food...
Could it just be stress? What could I do to make him better?

did you always have just the 1 panda? cory's are shoal fish, and depending on personality may or may not do well on their own. if he was once part of a shoal, then he might be horribly stressed now. make sure he has plenty of places to hide.
