60 gallon 4ft
2 occ clowns paired.
1 purple firefish
1 tail spot bleenie
What I want to add.
Exquisite Fairy Wrasse*(Cirrhilabrus exquisitus)
Bluehead Fairy Wrasse*(Cirrhilabrus cyanopleura)
Multicolor Lubbock's Fairy Wrasse(Cirrhilabrus lubbocki
Orange-Back Fairy Wrasse*(Cirrhilabrus aurantidorsalis)
Can I add any of these wrasse? What about female wrasse how many? Species?
Adding any one of those fairy wrasses should be fine; adding all four of them will not be. If you can find a female pairing for the one you choose, that will likely be fine as well, but only a single female.
