None. A single goldfish should have a minimum of 75L. You would be better off keeping small tropical Freshwater Fish.

A goldfish can live in an opaque glass tank as long as you keep up with necessary water changes. Like a small outside garden pond goldfish are only viewed from the top.
an aquarium or a fish tank
Rule of thumb is to not mix tropical fish and goldfish.
No. A 10 gallon tank is barely big enough to keep a single goldfish in.
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.
no they need at least five gallons each. a thirty gallon tank is a good size tank to keep goldfish in.
Most people would keep goldfish in a bowl or tank, filled with water. You can always add scenery such as pebbles plants and castles :D
7....But you should keep an good watch on them.
No the male will eat them keep them separate them until they can't fit in the mouth of the goldfish.
A total of four mollies can be found in the water tank
Does your snail have algae on it? Goldfish will eat anything that "grows" in the tank. They will eat turtle droppings, water scumm, algae, anything! That is why they are called bottom feeders.
