When I acclimate my fish, I always cradle w/ my hand and put it in the tank, no net.
There's a pic in my galleryof this.
Years ago I had a maroon that loved to be inside my cupped hand, and everytime I put my hand in tank she would swim into the palm of my hand.
So, there are some that are nicer than others.
Now the maroon I have now, bites my hand, draws blood, HATES when I scrape coraline in front of her nem.
But she takes good care of her nem and isn't mean to other fish ...yet, so I deal w/ her.
There's a pic of a baby maroon in my hand in my gallery.
Good luck to you.
