Size depends upon species. Most common species stay barely above three inches. Some get about twice that size, some even smaller. More common ones get no bigger than many of the aforementioned examples. Whether or not they are "happy" in harems is purely subjective. They may not "flash" as often, but it seem to have no real impact on their longevity or suitability in aquaria. They do well singly or in harems.<a href=showthread.php?s=&postid=7387888#post7387888 target=_blank>Originally posted</a> by Ironsheikh
flasher wrasses get pretty big plus they like harems to be happy.

fairy wrasses are always nice, atlantic pygme angles(had one didnt nip at anything but clams) or hell 24g is big enough get something like a potters angle. any goby/pistol shrimp combo is cool, if you can find em blue cardinals are sweet, basselets, citron gobys, if you dont like percs how about a maroon?
as far as shrimp go, i always like fire shrimp and harliquins(sp?)
I recently added a possum wrasse to my 30g. Cool fish but pretty shy as he tends to swim in and around the rockwork. Rarely ventures out into the middle of the tank, especially when I'm around.<a href=showthread.php?s=&postid=7390480#post7390480 target=_blank>Originally posted</a> by Clarkii3
possum wrasse look awesome, great fish, im going to get one of those, would it also be possible to get a perc also? so purple firefish,possum wrasse, and a perc. does it matter if i add the wrasse before the perc?

Another fish that I recently picked up and would highly recommend is an African Leopard Wrasse (Macropharyngodon bipartitus). Gets to about 4" max and a very active and beautiful fish.
