I have 7 halichoeres wrasses along with 2 leopards (m ornatus and m moyeri) and a harlequin tusk for a total of 10 wrasses in my 180, plus a few other fish. The list includes h iridis, h melasmopomus, h chloropterus, h chrysus, h melanurus, h biocellatus, and h timorensis. Have to say, I would prefer something more colorful than the chloropterus and timorensis. I added the chloropterus after the others were all established and had zero increased aggression, only stayed in the acclimation box for a day.
I'm looking to add xenojulis margaritaceus and coris venusta to complete my wrasse collection.
Needless to say, easily my favorite fishes. My favorites are probably the radient and earmuff. I really like h rubricephalus but have never found a healthy specimen locally (I will only buy wrasses locally).
