I got a free 35 gallon tank from my aunt. My friends little brother has a common goldfish that's not being well taken care of and I plan on adopting it. I am open to getting a bigger tank in a few years but I don't have the money right now. I would like to add another fish to the tank to keep the goldfish company and possibly a snail but I honestly have no idea what fish would be the best fit. I plan on having some kind of dirt or sand on the bottom of the tank with lots of plants as well.
