i have a yellow tailed damsel and a six lined wrasse.
the damsel has minor nips on his anal fin. i belive it is the wrasse but i could be from the store not sure. if it is the wrasse would it help to add a few more damsels. so they can school up and make more than one target for the wrasse. the wrasse was introduced last.

Sounds like it makes sense but it won't work.
Yellow tailed damsels are pretty aggressive fish for their size and very territorial.Adding more will lead to infighting as they grow bigger and start staking out territories in your tank.You'll also find it impossible to add any more fish once these fish make your tank home.New introductions are immediately attacked and either constantly chased or killed outright.
The sixline wrasse can also show nasty behaviour especially to fish that like dodging in and out of the rockwork but i think the damsels will kill him off in time anyway.
