I'm with squirrilah, it never hurts to have a sponge filter or two ready to go for QT or any number of other reasons. I've got at least 2 sponge filters sitting ready and waiting at all times cause you never know when you need to separate fish.
That is pretty normal. The only danger to the fish is stress, being killed, or having worse damage. I have a Red shoulder who is tore up just like that right now.
If you have a hospital tank, that would be good. But when you re introduce the fish it could happen again.
Generally once the fish has taken the beating they back off, unless they really want it dead.
It's pretty normal for new adds to get picked on the first two-three days.
I would treat the tank with Melafix, it helps regrow damages tissue faster. And prevents secondary infections. Prima fix is also a good add, if you start seeing signs of fungus.
Next maintain clean perfect water. And hope for the best.
I think it depends on the mbuna's personality, but it can happen frequently. You may consider investing in a hospital tank in case it happens more often. I've had one issue in the last few months that I've had mbuna.
I do still have my first tank which is a 8G with a tiny HOB filter.
I'll consider setting it back up if things get desperate but I have no plans with it right now.
