One or two would be just fine, provided you have a few females
They could well be spawning at this time of year.
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.
Goldfish are very aggressive consumers and have extremely short term memories and so could not be a very effective "comrade".
Only if the "feeder Goldfish" - which is usually just a mutt bred Common/Comet Goldfish, is very small and the Telescope is an adult. If it fits in their mouth, that's where it will end up! However, "feeder" Goldfish have the potential to get over 10"-12" excluding tail fin, and a large one of these could very easily fatally injure a more fragile fancy Telescope Goldfish. The two varieties should never be mixed.
Periadioc Comet
could be many? does it have "whiskers"?>A koi Does it have a tail fin that seems small for it's body?>Strong possibility it is a comet Does it have a normal sized tail fin?>Maybe a common goldfish Does it have a split "upside down v" tail?>It is a fancy variety
Unlike humans, telling the gender of a goldfish actually takes some knowledge. Do not pay attention to the color or the fins. Female goldfishes are actually bigger than the males (especially with their eggs). Males have mid-line ridges on their undersides. With all these in mind, the easiest way to tell is by their spawning time. The female opening will be bigger and heavier.
could you put comet in your dogs bath water
No
No. It is possible for a comet to leave our solar system, but not the galaxy.
Definitely. It certainly could, if it wanted to.
Go to the plaza then go to the goldfish zone then there is four places you could go through in the goldfish zone
