My poor sixline wrasse

Couple of days ago I added a sixline wrasse in my tank... And today I had noticed that my Yellow Tang is missing a little piece of his top fin, but my sixline wrasse is looking bad! His left fin is almost all chewed up... his top fin, left fin and back fin are all missing pieces..

My question is do they grow back their fins? and what should i do? any medications or anything? Should i remove one of them from my tank?

He swims are fine but im pretty sure he has difficulties..

 

They normally heal pretty quick. Don't worry, just fed them well for the next couple weeks.

 

would you say they will stop fighting tho? I dont see them being aggressive..

 

They will have a truce soon.

 

i hope so! thanx both of you! +k
