i believe it's 20g for the 1st fish then 10g for every one after that, so if your tank is 55g then 4 goldfish would be enough. there's a calcualtor above to work out tank volume.
that's for goldfish. If you want something like mountain minnows then it would be a lot more fish.

If your going for coldwater "because its easier" its not, the only main difference is the temperature both need filters and regular maintenance. A 4ft tank would be nice for tropicals but if you want goldies because you like them go for it But as above said with goldfish its 20g for first one and 10g for each after it and a big external filter because of all the poo

Just to point it out, all are referring to fancy goldfish because common goldfish will out grow a 55 g

 

[FWFishLover]

do you mean fancies or comets? comets are the once that sale for likes $0.13 or at least where i live they do.

no, i'm getting the 8fter for tropical and wanting to keep coldwater in my bedroom - just a smaller tank (4ft) just wondering how many common goldfish, shubunkins, etc i could keep?

Commons, shubunkins and comets are all single-tailed goldfish and all will outgrow a 4 foot tank. The smallest of them should easily reach a foot long and so would need a 6 foot tank. It is absolutely not unheard of for comets and commons to hit two foot long. In short - these are pond fish and should be treated as such.

If you wanted fancies, I'd say go for three. Many people will say 20 gallons for one . . . but I've seen a 10 inch long fancy goldfish in a 20 gallon tank and it is NOT a pretty sight. Three will look empty to start off with but with a good background, interesting plants, wood and rock work and three large, beautiful goldfish, it could look amazing.

Get a good filter - you'll need a large external for goldies.

Completely agree with Assaye above.

 

[fishfan91]

thank you for telling me this, do goldfish produce lots of dirt?

 

[waterdrop]

Yes, like other animals that eat only plants, they have to move a much larger volume of organic plant material through their systems to extract the amount of chemical bond energy that would come from a smaller volume of higher energy animal protein. So the eat a ton of plants and drop very large volumes of waste.

Yeah, they poo a LOT.

You'd need a filter that can handle at least a 6 foot tank.

I heard undergravel filter with powerhead will be okay in 4fter?
