i actually beg to differ about the 55G comment.

The pond we have in our yard has 6 or 7 small comets, and this year we have a 125G set up for them in the winter, but in the past we have housed them in a 55G in the basement with loads of floating plants, 24/7 lighting (blacklight), and only food was from the basement, meaning lots of flies, spiders, etc at all times.

Every spring, we would come to get the comets to put into the pond, and we would have 5 or 6 more than we had left. Usually the smaller or unhealthier looking ones would become food for either the cat or one of the bigger fish in our household, since our pond isn't big enough for many more fish.

But anyways, our goldfish have bred in a 55G, so it's not impossible.
