chromis tail bitten

Well was on my lunch break today, one of my blue chromis, his bottom tail is shorter then his top tail, im assuming one of my other fish bit his tail, im assuming its the midas blenny i have, the one that got bite, he always picks on my other chromis, he chases him around sometimes but most days there fine, maybe he got sick of it and toke a bite out of his tail lol, anyways all my fish are swimming together just fine and they seem to becoming good friends, besides my gramma, he likes to just swim around his sleep area. But long story short, will his tail grow back? its not a bad bite, just silghty shorter then his top tail? He is swimming fine just like the day i got him
