keep in mind some fish change gender after matting so it would be hard or rare
Put other fish in there and keep feeding them regularly and keep the pond clean.
I would say no as goldfish grow to be too big for a 1 gallon tank and to reach sexual maturity they would exceed the recommended occupant size of the tank.
With each other to create a crossbreed? No.
yes you can
yes it is depending if the fish gives burth to live young then its not possible !!
Not happily or healthily. Those goldfish need at least 30 gallons of space to live happily and have a long life. If you do successfully breed your fish, remember to remove the babies ASAP. Goldfish like to eat their babies.
A common goldfish can be bred with a red cap oranda fish. When these fish breed, there is a definite courtship ritual.
No. They are completely different fish.
Wouldn't recommend putting a goldfish in a 5 gallon tank-regardless of what type or size of goldfish. This is because the goldfish would be stunted causing it to have an untimely death. The condition in which a goldfish is "stunted" is where the fish adjusts to its tiny environment so much as to stop growing. The fish will stop growing on the outside but will continue to grow on the inside. Goldfish are naturally messy and create a LOT of waste. This factor would cause the tanks water to be poluted which inturn could kill not only the goldfish but possible your mollies too :(. Two mollies is enough for a five gallon tank. If you truly want to get a goldfish you will have to house the goldfish in a 10-20 gallon tank with very good filtration
A tiny little 10 gallon tank is no where near large enough to breed/spawn any kind of goldfish. It is not really large enough to house one goldfish properly.The base stocking rule in fish keeping is "1 inch of fish needs a MINIMUM of 1 gallon of water" Goldfish grow to at least 10 inches so the minimum size for one goldfish would be a (nominal) 13 gallon tank. (No one fills a tank to the brim) That would actually hold about 10 gallons.
The rule of thumb is 1 gallon per 1 inch of fish. But of course if you have bigger goldfish you will need more room. So for larger fish, go 1 gallon per 3 inches of fish.
Goldfish release growth-inhibiting hormones into the water they live in: the more goldfish in a smaller space, the less likely they are to grow. For instance, if I have a common goldfish in a 5 gallon tank, it will grow to about the same size if I had 6 of the same fish in a 30 gallon tank. But leave that fish alone in a 30 gallon tank, and it will grow larger. This is why pond goldfish grow bigger. But goldfish won't grow at all in seawater; they aren't saltwater fish.
20 gallons for one fish and 10 gallon for each addition goldfish. See the related link for further information.
Goldfish are pretty easy to keep.
A small fish bowl is bad for any fish. You need minimal 5 gallon for a single betta. You need minimal 20~30 gallon for a single fancy goldfish, 40~55 gallon for a single common goldfish. Because fish produce ammonia and it is toxic to themselves. Goldfish has such large body mass, so they produce enormous amount of ammonia. You must have a good filter system, and do a nitrogen cycle first before adding any fish at all.
You need to provide 1 gallon of water per inch of fish. Goldfish get along fine with other goldfish.
