Fresh water that is free of impurities and cannot be tap water. You can go to the grocery or any other place to get Poland Springs water and get a filter at a pet store. Then you are ready!
note: if you would like to use tap water, use a "water conditioner" to remove chlorine and chloramine.
Yes, it is much better than tap water. Just make sure that you add whatever conditioners you usually put into the tank after adding the distilled water. Distilled water will not have chlorine in it, but it will also be missing things like very small amounts of salt that can be good even for fresh water fish.
fresh
Depends on how many blades of grass there are, what type of grass it is, etc, doesn't it?
the most important two things we need are water and sun, we need water to live
This is a quetion that i need an answer for. It is for a science fair project.
Materials that dissolve into water. Like sand, soft rock etc. If the material does not dissolve into the water or any type of liquid then that won't need filter paper. You can just use a sieve just to make your lives easier.
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..
fresh water
None, goldfish are cold water fish, so having a tropical fish as a tank-mate just wouldn't work because tropical fish need to live in warm water.
Tap water is perfectly OK for goldfish. All you need to do is make sure the added chlorine/chloramine is either chemically removed using a chemical additive available at petshops or if your water provider does not use chloramine all you need to do is let the water stand in a bucket for a few hours or overnight and the chlorine will evaporate off.
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.
You need to provide 1 gallon of water per inch of fish. Goldfish get along fine with other goldfish.
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 :)
Yes a ryunkin is freshwater. All types of goldfish are freshwater regardless of being a singletail, or fancy type
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.
A goldfish is not from the fish type of anabantid (labyrinth fish) who would actually really drown if they do not swim up to the water surface to breathe.
