One of my cory cats found his way behind my moss wall, and hurt himself trying to get out. it looks like he rubbed a really bad blister on one of his sides trying to get out, and his swim bladder is causing him to sink pretty fast. I have no clue what to do. I have already moved my moss wall so that it can't happen again. Other than that I am clueless.

Since I don't know how long he has been back there, the first thing I am going to do is try to feed him. I held him a few minutes ago to look at the blister. Do you see any problem with holding him up some more? Are there any other suggestions?

I would really rather not have a fish die when this tank is only one week old.

Is he swimming upside down or sideways? My one of my cories died in almost the same way.

He is swiming fine, except he struggles to swim up. When he sits on the bottom, he tilts to the side until his fin gets him stable again. I have seen him try to swim to the top for air several times now, too.

I also tried to feed him but he isn't hungry. All the other fish were though. It's nice to see them swimming around.

So he made it through the night but barely. His swim bladder seems at least balanced with the tank, so he doesn't sink anymore. However, half of his tail fin is now missing. What in my tank would have done that?
