Yesterday I bought 13 black neons. I haven't had fish in quite a while, so I was pretty excited to finally get them. When I asked about ich and such they informed me they'd been at the store for quite a few weeks and shouldn't have any problems. As it turns out 4-5 are missing gill covers and 1 has a misshapen spine. Looking from above it looks anything but straight. Obviously I can't do much about the spinal issue, but is there anything I can do to help these guys regain their gill covers, will it cause issues down the road, etc?
