wounded yoyo

[millym]

hi
noticed yesterday one of our yoyos has a wound on his 'cheek' just in front of his gills towards his nose theres a patch of rawness, looks like its been scraped. he also looks a bit stressed - is staying grey instead of usual black & cream. i put in some melafix yesterday & this am & it does look better but im just wondering what could have caused it.is it likely hes just scraped himself on the edge of a rock or something? our substrate is all smooth rounded small stones, or could it have been caused in a fight with the other yoyo. can they injure each other if they have scraps
we've never seen any other fish harrass the yoyos, the injured one was added about 3 months ago to replace one we lost & at first the pair of them were always scrapping but they settled down quickly & lately have been 'hanging' around together.
i know im just being overcautious but we dont want to lose this little fish.

If it's looking better with melafix, that's great. Maybe he was startled or something and scraped himself on a rock. They can move pretty quickly while playing or scared... Hope he heals for you.

thanks
yoyo looks MUCH better this morning - just a tiny mark on his face now & is out & about up to his usual mischief, and back to his normal stripey self.

I couldn't be happier. I love and hate mine He's very cool and I've had him for ages but he can be a snot
