Cory looks "off"

Did anything else die in the tank? There are a few diseases that will leave a spine bent.

I can't tell from the picture. Sometimes little genetic defects happen. If the cories are raised by the bunches, it could have been missed when it was time to cull. He could still live a long happy life. I have an albino aeneus whose snoot wraps around and under. Looks really weird and you'd think she'd have trouble eating. She can't really use her barbels, they are on the bottom of her chin, underneath, not out in front. Not! I've had my albinos for years and she's just as fat as the ones with the normal mouths.
