Sorry for such a rookie question that has probably been asked several times on this forum, but I couldn't seem to find a consistent answer. I am buying fish for an aquarium I have at my job (I teach) and there's no pet store in the town I work at. I have to buy them from my local pet store which is almost an hour away from my school. Therefore, I'd be buying them after work, holding onto them, and introducing them into a cycled tank the next day. Do you think they'll be okay in the bag for about 12-15 hours? Thanks!
