My grandma has this tank the used to keep goldfish in. I want to have my own aquarium, but I'm not sure what fish could be best kept in this size tank. It's about 3 gallons, according to Google. I'd prefer multiple (small) fish in a tank, but oh well. Any advice welcome! (I'm not planning to keep the items that are actually in the tank, rather buying my own with extensive research.)
