I have an ID request, and thought I'd also give an update. My Isosceles wrasse made it through 4 weeks of quarantine, and has now been in my display for a few weeks and is doing great. She has also colored up a bit more since I got her, so I'm still hoping she will turn into a male. She's a real docile fish, and slightly shy, but I do get to see her a lot. She also has some fire in her belly, not holding back if any of the other wrasses give her a hard time. My Lubbocki and her are quite evenly matched in size and chases each other around sometimes. She flares her fins, puffs up her throat and intensifies her color. Then onto my ID request. I was wanting to get another Halichoeres wrasse, and was also looking to add a green fish to my tank. I settled on a Biocellatus due to it's small size and temperament, and special ordered one from a store's supplier list. After taking a good look at the fish I received, I'm not convinced it is a Biocellatus. It is however still a beautiful fish with a very friendly personality. I'd want to keep it, but just want a positive ID so I know what I'm getting myself into, and whether it might be a risk to any of my other livestock like shrimp and crabs. My guess would be Halichoeres annularis or Halichoeres marginatus? Can anyone please help with a positive ID? I see Marginatus gets quite big and might be a risk to the inverts. Any info on Annularis, if that is what I have? Here is another one giving a better view of the tail fin.
