Neon Tetra Advice

[hello kitty]

I have some Neons in my tank, it looks like one may have been attacked by something the day before yesterday as one of his fins looks damaged and he is swimming about in circles and upside down. he is still eating and everything fine, i just wondered if anyone knew what i can do to help him??

many thanks

What other fish are in your tank? How long has it been set up? What are your water stats? Have any new fish been added lately?
