I have 5 goldfish in..

Question

i have 5 goldfish in a 20 gal tank

it looks pretty empty

how many is the max i can put in there

Answer 1

it depends how big they are. there is a rule of thumb that you need one gallon of water for every inch of fish. but that doesnt mean you could stick them in a one gallon tank. they still need room to move around in.

Answer 2

It won't look crowded when they're about 8" long a piece, you are overstocked. Stock with view to adult size, not juvenil size.

Each goldfish needs 20 US gallons to themselves. Rehome 4 of your goldfish or get a larger tank. As they mature you will experience more and more water quality problems.

Answer 3

That's WAY too many goldfish for a 20 gallon. You should only have ONE if there, if that even. Goldfish get a whole lot bigger. If you keep them all in that tank they will eventually die prematurely. They'll die because their outsides will stop growing, but their inside won't. It's something that happens to a lot of goldfish because owners don't research their fish before they buy them. Id suggest giving them away to proper homes if you can't get a larger tank or an outdoor pond.

Answer 4

you need space for them to grow up

Answer 5

like 20  

Answer 6

goldfish really need like 20gallons per each one.....

Answer 7

Do you have a 20 or do you have a 40?  5 in a twenty is pushing the limit. 8 in  a forty (as long as they are the fancy/pearlscale, fantail) they are fine.  While the fish are small it looks like there is pleanty of room, the fish will grow into the tank and quickly.  If your tank is 40 no more than 8 goldies.  

Goldfish do not need 20 gallons each to live long happy healthy lives.  Not all goldfish are pond fish.

the most important thing to remember about goldfish is to have pleanty of dissolved oxygen and a clean tank with weekly water changes.  Your fish should be fine.  Remember most fancy's don't get 8 inches or over.  the average body length is around 6-7   8 is a large figure

Answer 8

the maximum goldfish (common? fancy? they grow different sizes)

is -2- and you really need a 30 gallon for 2. Goldfish grow very big and are very messy.

You have past your max, my advice? Get a bigger tank or give away three goldfish.
