I have that fish for 4 days only.

Where do you think us smrt fishy pple got the idea?

You gotta catch them pretty fast as far as I know, but there aren't many studies on ornamental marine fish so most of our methods are anecdotal at best. Personally, a fish like a CBB which is known to often still be caught with cyanide I would have dipped in MB during acclimation just as a precaution. MB is quite gentle on them, so I see it causing no further stress or harm. More of an anti-stress dip in my experience.
