Iv got a filter in mine, so i do a 40% water change everyday (that's where you take 40% of the water out and replace it with clean water) and every 5days to 1 week i put it in the spare tank while i clean its normal one, and i clean all its toys too, then stick a lamp above the tank whats just been cleaned so the water isn't too cold for it. Then when the water isn't freezing, i put it back in its old tank ^_^
every other week
You can use clean tap water for your goldfish, but not dirty or used water.
No, a gold fish is clean
Once a week :))))) i have experience
Keeping the water clean in your goldfish aquarium will not only make your fish more likely to spawn but will also greatly improve the health of your fish and any potential fry, so yes you should keep your goldfish's water clean for them to spawn.
There is really no commensalism that takes place between goldfish and other creatures. Occasionally, goldfish will clean their homes by eating leftover food and waste products.
Usually when they are about 2-3 years old. Goldfish can also die if you don't feed them enough, or too much. When goldfish are not kept in a clean habitat, they can get sick and die. Make sure to clean your goldfish tank at least once a week. Remember, goldfish mainly die from aging
every 3-4 weeks
No bettas live for 2 years. goldfish live for long as 25 yaers if conditions are clean.
about half an hour to an hour
no it isn't really, but you have to clean it regularly to make sure it is very clean for them
Stop doing a handstand. If your goldfish is floating, it will float to the top, not the bottom, therefore, you must be upside down!
