Yes
(I keep fish too :P)
No, that is only about 6 gallons; fancy goldfish need at least 15 gallons each regardless of how tiny they seem when you buy them
Tetras look great in schools of 8 so I'm guessing tetras are the best in groups, however there are also fancy goldfish for individual beauty. Hope this helps -goldfish keeper
Shrimp and goldfish are not compatible in a freshwater aquarium. Goldfish are known to eat shrimp, so it is not recommended to keep them together in the same tank.
an aquarium or a fish tank
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 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 and shrimp are not compatible in a freshwater aquarium. Goldfish are known to eat shrimp, so keeping them together may result in the shrimp being eaten. It is recommended to keep goldfish with other fish species that are similar in size and temperament.
Goldfish and turtles are not compatible in a shared aquarium environment. Goldfish are sensitive to water quality and turtles can produce waste that can harm the goldfish. Additionally, turtles may try to eat the goldfish or harass them. It is best to keep goldfish and turtles in separate tanks to ensure the well-being of both species.
Goldfish may be kept in an uheated fresh-water aquarium. They are considered ill-suited to live in a heated tropical fish tank, as they are used to the greater amount of oxygen in unheated tanks.
Yes, for they are both Fancy Goldfish (It's bad to keep Comets with Fancy varities because most likely the comet will become stressed and die).
