I’m heading upstate to NY to visit a fish shop. They close on sundays and I’ll be leaving Sunday at 12 and getting back at 2. They close regularly at 6 so if I buy Somethjng from there (coral or fish) at 6 before they close, how would I be able to hold onto it so it lives when I get back? I have many boxes from live Aquariua that have shiny lining on the inside and boxes that have styrofoam lined inside. I can also bring a small pump but will this be enough?
