Acclimation box should i get one.

Got a bunch of fish coming in soon and wondering if an acclimation box would be useful. Adding a tomini tang, leopard wrasse and mandarin. My fish are not very aggressive but who knows what will happen. I plan on dumping them all in at the same time.

Why set the mandarin free?
