If I have 25 goldfish, what size fish tank should I use? Measurements please!?

Answer 1

goldfish grow to fit their tank, but so that they dont' get stunted (and get sick and die), you need a minimum of 10 gallons of water per fish, until they are 5 years old. after that, you might want to double it. Goldfish, if kept properly, can live from 15-20 years. i have a 7 year old fantail in a 20 gallon tank by himself, and he's never been sick (knock on wood!!)

try getting a 250 galon tank, or 5 or 6 50-60 gallon tanks. with that many fish, you will want at least 2-3 large filters per tank, make sure that you pay attention to the minimum gallons per filter on the box. you're in for a very expesive hobby!!!

good luck!!

Answer 2

Goldfish are very messy fish that grow to be very large. In an ideal world, I would recommend 20 gallons for each full grown goldfish. If they're still relatively small, you can get away with maybe 10 gallons per fish for now, but you will have to upgrade or sell some of your fish later on.

Honestly, 25 goldfish is too many fish to sustain in one reasonably sized tank anyway. I would recommend either finding some of your fish new homes or getting two 55+ gallon tanks (the bigger the better in this case) and have about 12 fish in each.

Answer 3

God 25 gold fish?
Why would you want 25 goldfish?

They would need an unimaginably huge tank, full size would need around 500 gallons. Just 2 alone would need around 50 gallons. Plus the filter required would cost you hundreds of dollars.

Don't get goldfish. PLEASE don't get goldfish.
If you want a ton of fish, get like 20 neons in a 20 gallon tank.

1 inch per gallon definitely does not apply to goldfish.

Answer 4

Goldfish need an absolute minimum of 10 gallons per fish. They are very dirty fish, any small tank will get dirty very quickly and it will be very hard to keep all of the water levels in check. With 25 goldfish, you will need a minimum of 250 gallons, preferably bigger.

Answer 6

With goldfish the bigger the fish, the bigger the tank.

http://www.petlibrary.com/goldfish/examples.htm
Surface Area = Length X Depth
Inches of goldfish = Surface Area / 30

Let's say your tank is 18 inches long, 10 inches deep, and ten inches high. If we multiply the length (18) by the depth (10) we come up with 180 square inches of surface area. Since we need 30 square inches of surface area for each inch of fish, we can keep 6 inches of fish. So I could keep 6 one-inch fish in this tank. Or I could keep 3 two-inch fish in this tank. Or I could keep 2 three-inch fish. Or any combination that adds up to six inches.

Answer 7

Goldfish need 10 Gallons per fish.

Answer 8

You'd need at minimum a 250 gallon tank and a filter that moves 2500 gallons per hour.

Answer 9

1 inch of fish to 1 Gallon of water is the rule of thumb. However it can differ if the size of the fish differ. Since yours are all goldfish, this rule should apply nicely. :)

Answer 10

1 gallon per inch of fish. Gold fish can grow much bigger so you will need more to accommodate them.
