I would not be that concerned about such a short drive. I would tell the LFS about your intended trip ask them to maybe use a bgiger bag with a bit more water etc. I would bring a cooler I would also place the fish on the floor.
Going be doing a planted, 50 gallon tank and here's my stock list. Please review and let me know what ya think:
(BTW the Betta will be the last fish to go in)
10 Cherry Shrimp
10 Zebra Fish
10 Cherry Barbs
6 Golden Molly (All females)
Is this over crowded?
The second I read your forum I went "over crowded"
Ok now you can get away with overcrowding on a larger tank a bit (even then you can't go crazy) but on a 5 gallon or 10 gallon it needs to be pretty strict.
Here's my advice pick one of the above single fish. As in you can have 3 danios, or 3...
