Don't forget renter's insurance. If you are going to have fish tanks and could do damage to property, it's something you might want to consider.
Yeah, good idea. With a small apartment you could probably get it for as low as $20 a month, maybe lower. A good idea if you're living month to month like you are- if something happened, like a fire or something, without insurance you could be screwed.
I suggest going to the dollar store for things like cups, plates, the grabage cans, things like that. Paper cups/plates will be MUCH more expensive in the long run, you can get a cup and a plate for $1 each, and some silverware. Much cheaper than paper/plastic.
