Clean water of course! Dirty water is full of pollution, and makes it harder for the fish to breath. Also, dirty water that contains high amounts of ammonia, nitrite, and/or nitrate can actually cause long term gill damage in goldfish.
fresh water
Unchlorinated water, such as bottled distilled water is best.
The best way to have clean water, is to boil it. Water purifiers are a close second, and although they still clean your water, they are not the best way to have clean water.
cold is better cuz when your in the ocean is the water hot or cold cold
It would depend on how dirty they are. Keeping headlights clean would be in your best interest.
Distilled water from you local grocery store or walmart.
No, goldfish are best with goldfish with the exception of weather (dojo) loaches, bristlenose plecos, and apple/mystery snails.Although goldfish can survive in warmer water temperatures, they are a "cold water" fish and not a tropical fish.
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 :)
i think that ketchup,lemon juice,vinigar,tomato juice is the best
1. Sweep or vacuum the obvious dirt 2. Mop with water. (Fill the bucket no more than half way, change the dirty water often, wring the mop well before placing on the floor) 3. Rinse the dirty mop well, then mix 1 cup white vinegar per 1 gallon of water. 4. Mop using solution. If water gets dirty, change out water with solution and continue.
