Goldfish can be divided into two groups, single-tailed and twin/double-tailed goldfish. A single-tailed goldfish is a variety of goldfish with a single tail such as the Comet, Common or Shubunkin (poor man's koi). These varieties are much closer to the wild form of the fish and as such are hardy but require more space. Twin-tailed goldfish are often referred to as fancy goldfish. Fancy goldfish varieties are more delicate and have a 'fat' appearance. Some twin-tailed varieties are the Fantail, Pearlscale, Ryunkin, Blackmoor and the Celestial-eye. It is not advisable to mix twin-tailed and single-tailed goldfish together, as the single-tailed goldfish are more active and swift and may bully twin-tailed varieties as well as forcing them to compete for food.
Fancy goldfish need at minimum 20 gallons for one fish, plus 10 gallons for each additional goldfish you are adding (thus 30 gallons for 2 goldfish); so the answer to your question is dependant on the size of your tank.
Cross-breeding can produce nice fry, but in many cases unless you are a breeder, the majority of the fry may not survive due to the amount of cross-breeding that has occurred already to get many of the breeds we see these days.
Some common breeds of goldfish are: the Black Moor goldfish, the Ryunkin goldfish, the comet goldfish, the common goldfish, the Calico Fantail goldfish, the telescope eye goldfish, the bubble eye goldfish, the pearl scale goldfish and the Oranda goldfish.
