I just got a 10 gallon tank, but it is bare, and isn't cycled. I wasn't going to introduce my fish Puffy until it was cycled and full of plants and the other fish were introduced, but since I just learned that my family is going on a week long trip, and that the only other housing option would be his 1/2 a gallon cup, I obviously chose the 10 gallon. But I'm worried how he'll react. There won't be gravel, or hiding spots, or plants, or a heater, or a filter, or a top(unless I can get to petsmart soon), so it'll be really empty and full of too much space. I might be able to dig up a really old tank ornament out of the basement for him to hide in, but that's it. Should I worry about him jumping or getting too stressed while I'm gone?
