Lots of choices in wrasse...got to love those guys. Part of what you pick will depend on what you plan to have in the future and your budget so always keep that in mind. Me personally, my favorite fish so far has been my Blue Headed Wrasse...great energy, not something that everyone has, and CHEAP...er. I think I spent like $20, maybe less on mine. Especially, mine was of the changed sex coloring, so he/she :lol: had a blue head, an oreo cookie :mrgreen: (black line, white line, black line), and a green body.
Just make sure you're not adding too many fish all at once; 1 every few weeks is a good idea just so you can allow your system to adjust to the added bioloads. Granted for your size tank, you have a bit more wiggle room, especially if you're adding pairs/small groups, but if you've just added three fish to a newly cycled tank, wait a bit and see what happens.
