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.
The Panda Oranda is simply another line bred member of the Goldfish family and if you breed one with another variety of goldfish you will get some that look like Panda Orandas, some that look like the other goldfish and some that carry the genes of one but look like the other and vice-versa. You would be reversing the years of work that expert fish breeders have done in developing the Panda Oranda in one fell swoop and at the same time you would be producing cross bred worthless fish.
Yes, two goldfish can live together in the same tank as long as the tank is large enough to accommodate both fish and there is enough space for each fish to swim comfortably. It is important to provide proper filtration and regular water changes to maintain good water quality for the goldfish.
yes
I think they are a little bit more bland than the regular ones, and I think they have less salt on them. That's just my opinion. They are supposed to taste the same though.
Goldfish should only live with goldfish with the exception of weather (dojo) loaches, bristlenose plecos, or mystery/apple snails.
They all originate from the same roots, but since goldfish that live outside are more used to the cold and other changes, I would say that goldfish that live outside are stronger and more likely to survive.
Goldfish and cichlids have different care requirements and temperaments, so they may not live peacefully together in the same aquarium. It is generally not recommended to keep them together.
Goldfish are meant to live in cold water, not the warm water in a tropical aquarium. This is a huge reason why goldfish and tropicals shouldn't be in the same tank.
Well, you gotta chose fish that live in the same conditions as the goldfish such as Koi. You could also do some researching and find out too.
yes they can. the black moore goldfish has telescope eyes as well and so they both suffer from limited vision and competition for food is not as one sided.it is not recommended however to put either in the same tank as a regular goldfish, as their eyesight is normal and they swim faster and so eat a larger percentage of food than the telescope or black moore.
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.
The plural of goldfish is goldfish. It is the same as the singular.
