It will continue to grow, contrary to popular belief, comets do NOT grow to the size of their tank, they continue to grow. Your comet will grow to be a max of 1 foot 2 inches long, you will need to give it at least 25 gallons to itself, it is inhumane to put a comet in that small of a tank and only give it 3.5 gallons to itself. They need at least 10 gallons when young and 25 full grown.
As big as jaces brain
One goldfish needs a 30-gallon tank, and an additional ten-gallons per additional goldfish. Goldfish can grow to be 10-12-inches long.
Absolutely not! Unless the goldfish is half an inch and going to stay that way you are seriously hurting your fish! A comet goldfish will get very big! you need at least a 55 gallon tank for that sucker! Try raising a smaller regular goldfish in a 20 gallon tank. You'd be far better off!
If by "comet fish" you mean a comet goldfish, you should not put anything in with it unless you get a much larger tank. A comet goldfish can grow six inches or longer, and will need a larger tank. Any tankmates should be cold water fish, like the goldfish. Snails will also get along well with the fish, but might get eaten. If it is a marine comet fish, it will grow up to seven inches, and will also need a larger tank.
yes
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.
Comet goldfish need at least 30 gallons each because of the type of fish they are (single tail), the fact that they can grow extremely long, and they produce a lot of waste.A fancy goldfish (fatter with more tails) need 20 gallons for just one fish, so either way, your 1 gallon tank cannot hold any goldfish at all.
Comet goldfish grow to be around a foot long. 120 liters is about 30 gallons so I say about 2. Get fancy goldfish because you could do even five in a tank that size because they don't get as big.
yes
depends, can a ten gallon tank live in a goldfish
If the goldfish is a fancy variety, it can live alone in a 20 gallon tank. Goldfish do not belong in tanks any smaller than this as they grow very large
Goldfish commonly grow to over 12 inches. The size of your tank would indicate that it is not really large enough for keeping goldfish in. The basic rule of fishkeeping is "1 Inch of fish needs a minimum of 1 gallon of water. Goldfish should really be kept in a pond.
Yes, but only for a very short time, for goldfish are known to grow rapidly.
