The top picture looked like small string like objects trailing off the fins which looks like anchor worm. If that was just from a bad picture and they are in fact just tiny white bumps on the fins then perhaps it is not anchor and the non-pathogenic white cyst like lumps I discussed in an earlier post. If you could get a clear picture it would make it easier to tell what it is or isn't. I don't want to see you medicate the fish for no reason if nothing is wrong.
If it looks like Steve's picture above then yes I agree 100% it is nothing to worry about.
