Just a note, but a 5 gallon tank is too small for a goldfish. They need at least a 20 gallon double-filtered tank, 30 gallons, double filtered, is better. That's just for *one* goldfish. Add 15 gallons for each additional. You're looking at a 35-45 gallon tank with filteration for a 90gallon tank.111188 said:Hi All,
I am a true newbie, just bought a 5 gal hex kit today. I just put washed gravel in, water, and chlorine remover, water. I am running the filter bio-wheel thing, and want to leave it run as long as necessary before I buy my fish, which will be a couple of small (1") goldfish I think. I have two questions. One is, I read above to buy some ammonia and add to tank. Do you mean regular ammonia or is there some kind of special aquarium ammonia, and how much to add to 5 gal? Two is does it matter whether I put in the charcoal packet in the filter during this cycling period? Told you I was new. Many thanks in advance
Goldfish produce a lot of waste and as they grow -- depending on the type, about 6-8" -- you will have to do more and more water changes just to keep the ammonia and nitrites down.
One kept in a small tank like that might live a couple of years -- if you are lucky. If it's kept in a proper sized tank it could live 20+ years.
I'd like to suggest that you get a smaller fish, such as a betta. They are ideal for 5 gallon tanks.
