I have had bad luck with the yellow fins they seemed to be very aggressive toward the other
Wrasse in my 125 I had a whip fin, filamented flasher,yellow coris,radiant,menalurus,yellow fin fairy and four Line they all got along with each other and avoided the yellow fin he was always flaring himself at them and taking a swipe here and there all others I mentioned are fine moral of the story is avoid the yellow fin fairy had a couple over the years a d all of them showed bad behavior
so I'm now up to
Elegant Wrasse
Mystery Wrasee
yellow coris (baby, just over an inch)
lubbocks wrasee
no issues at all and they've been together for a month, I'm hoping to add one more, either a melanrus or radiant, I'd like to add a higher end wrasse, like a flame, rhomboid or Lineatus, but I'm too **** scared that a $200 fish will jump out of the tank, even with covers, so I might get a scott's fairy wrasee if I can find a decent price ($100 or less)
