I am thinking of going out at the weekend and buying a proper tank for Goldie, the goldfish - dont blame me for the name please!
What sort of tank should I be looking for? Do I need one with lights - the one it's in at the minute doesnt have that. Also I am thinking of getting it a little pal, it seems a shame to keep it on its own, so if I am going to do that, how big should the tank be?
What type of fish would go best with it? I am presuming it would have to be another goldfish, but do some grow bigger than others?
