I got the fish today, he is doing really well,

but it turns out he was only in a mason jar they decided to
keep the tank. He is going to my grandparents house before the amusement park tomorrow, but my grandmother
who is picking him up to take to her house has to get a few things to do before she goes
home

so he will have to be in the car for couple hours!!

So I am putting him in a small cooler so it will not get too hot, he will be in his jar and surrounded with
the air filled packing stuff, and bungge corded down to the seat so it won't jiggle around to much, the air will be on so it won't get hot on the inside of the car unless the car is turned off is this plan O.K. or do there need to be alterations?? And do I need an ice pack, it will be over 100 degrees out side PLEASE HELP ME!!!!!!!
