Yes. Put the Wrasse in the box. Take him out of his comfort zone.I think they already paired up, I stopped by my LFS and bought a smaller acclimatization box ( the one i have is huge and it cover a lot of light and interrupts with the flow ) to see if I can put the six line in that one and give time for the shrimp and the goby to make their cave and so the six line relaxes a little, what do you guys think?
