My shark is dying. He is upside down. He is still alive because another fish was pecking at him. What can I do to save him. Please help me!

Have you tried changing the water?

I'm sorry, I wish I knew of a way to help.

Please check back often, hopefully someone will come along that has some ideas. I don't know anything about fish.

Good luck.

I hate to say it but I don't think there is much chance for your fish...
If he was just at the bottom I would say a water change and checking all of the levels in the water (ammonia, ph etc) might help but him being upside down... not good.
Sorry.
