Injured Cory?

[bex1]

hey i bought 4 baby peppered corys from a lfs 2 days ago and theyre in my quarrantine tank. i have just noticed that one of them has a bent back/spine along the tail, he doesnt seem to bothered and swims fine, but seems more lethargic than the others and often sits around doing nothing.
has he been injured or is he ill?
thanks

Any other symptoms?
Does his underside/belly, look sunken, is he eating, are the eyes noticably protruding?

Do you remember if it was like that when you bought it and maybe didnt notice until you got it in the quaratine tank?

he was like that when i bought him!
also there are no other symptoms eg no sunken belly, or protuding eyes but he does seem more dosile than the others and slightly smaller, he often sits on the bottom looking like he's dead! but then he swims off for a minute or so and then rests again!.
Thanks for your replys, any ideas on whats wrong with him and how i can help him?
cheers x x x
