Goldfish do not need running water, but they do need a filter that cycles the tank water through filter media. In addition, you need to change at least 50% of the tank water each week making sure that the new water is the same temperature as the old water, and that you add in the recommended dosage of water conditioner per the instructions on the bottle.

It depends on the goldfish.. For ones that stay small you should have at least 10 gallons.. The bigger the goldfish gets the more water it needs. Those one and two gallon bowls do not cut it..
You need to provide 1 gallon of water per inch of fish. Goldfish get along fine with other goldfish.
My Fantail Goldfish did that alot the first time I got him. I think it might be that they need to relax or they might be scared.
Goldfish and turtles have different care requirements and habitat preferences. Goldfish need a tank with clean water and a filter, while turtles need a tank with both water and a dry area for basking. Goldfish prefer cooler water temperatures, while turtles need a warmer environment. Additionally, goldfish are primarily herbivores, while turtles are omnivores and require a varied diet.
HOPE THIS IS HELPFUL
goldfish will survive in tap water but it is best to put a bit of chlorine control in the water plus you will need a filter if you want the water and tank to stay cleaner for longer :)
It depends on the fish. If its a tropical fish that is accustomed to salt water, you need salt water and you need to keep the water at a warmer than norm temperature. If its just a regular goldfish, freshwater at room temp should do just fine.
Yes, like all pet fish, goldfish need more oxygen than can be provided by just a bowl of water.
Goldfish and turtles have different care requirements. Goldfish need a tank with a filter and regular water changes, while turtles need a tank with a basking area, UV light, and a varied diet including vegetables and live food. Goldfish are cold-blooded and need cooler water, while turtles are ectothermic and need a heat source to regulate their body temperature.
Yes. goldfish breathe water so if a goldfish is out of water it cant breathe so it will suffocate
Because a comet is a single tailed goldfish, and can grow very long, it will need at least 30 gallons on it's own
