I know it's easy to forget your cooler or some will think if I don't bring a cooler I won't buy any coral=spend the $$$, but that doesn't work!!! You will see a coral you will not be able to live without, buy it and walk around for 5 hours with the little guy in your hot little hands! There is a big difference between 78-80 degrees and our 98.6 degree body temp. He in there with the temp going up thinking you are boiling him/her to death. Do both of you a kindness, bring a cooler, you SAVE $$$ and your coral has a chance to live.:yay:
