I bought a 55 gallon tank with the intention of making it a corydoras catfish species tank, and I went to my local fish store to buy a filter and everything. The manager sold me 3 comet goldfish for cycling purposes and told me to bring them back for store credit in about 3 months so I can get the cory cats that I want. But, as I started to take care of my goldfish, they each developed their own little personalities and I got attached to them. I just don't have the heart to take them back where they'll be sold as feeder fish or put in a bowl as a pet for a child. So i'm not going to be getting rid of them. But to the point, what are some interesting types of coldwater fish I can put in with my goldfish? I had to scrap the ideas of getting cory cats for obvious reasons.
