I went lastnight & bought a 6-line ($30) and payed a little more than I should have due to the fact that all the F.S.'s in the area can't seem to keep them in stock for more than 3 days before they are sold out. My blue sided fairy wrass is behaving but my purple psudochromis bit the little 6-line in the mouth just seconds after added. Now today his lips are showing puffy white marks. It is eating but I fear that within a week it might not make it due to stress and damage from my constantly harrassing purple psudo. Catching either one will prove to be impossible so now I have to play the waiting game. I hope that the lil guy makes it as that would be one expensive meal for the brittle star. thanks for all your input, I think i'll look into adding a mandrin within the next few days. But which one??? green or spotted??? both are wicked looking. Guess I'll let my 3year lod daughter pick this one. Thanks again everyone.
