Hi Luc,
The 3 chaoti wrasse look lovely, very very hard to keep long term - but I have a feeling you know this

. I also think if any one can keep them, you can, as you appear to have a good track record with fish.
I am sorry to let you know that the acropora echinata frag I got off you did not make it, it very slowly stripped from the base up, I made some frags and tried them in my frag system but they also went.
Good luck with the new wrasses, I look forward to seeing more updates - please do some more photos and videos when you have the spare time.
All the best,
Tony
