Can you breed goldfish in a one gallon tank?

No. A one gallon tank is not appropriate for a singular goldfish much less multiple. A ten gallon tank is the bare minimum for a singular goldfish and breeding would require a tank of twenty gallons or more. A one gallon tank cannot handle the chasing that proceeds goldfish mating nor maintain a water quality that is suitable for raising goldfish fry.


Can an oranda goldfish live in same tank with regular goldfish?

Yes, but your tank size needs to support it. If you mean that a regular goldfish is a long single-tail goldfish, then you need at least a 40 gallon tank just for the 2 fish due to the size potential of the common goldfish. If you mean a regular goldfish as in a round bodied fantail, or perhaps a ryukin, then you need at least a 30 gallon tank for the 2 fish.
