between 5-10 gallons per inch of fish.
A single adult goldfish needs 20 gallons and another 10 gallons per addional goldfish (so two goldfish need about 30 gallons but something between 25-35 gals would be good). As babies they one can survive in a 10 or 15 gal but the tank should be upgraded as soon as possible.

∙ 14y agoTwo goldfish should be given a tank of at least 30 gallons. A more ideal tank size would be 40-50 gallons. Anything larger than 50 gallons is just icing on the cake.

∙ 14y agoGoldfish produce more waste then other fish, conventional wisdom says 10 gallons of water per fish, however I've kept two goldfish in a ten gallon tank for years.

∙ 13y agoIf there still small you could put them in 10 gallon tank, over time you'd need to upgrade to bigger tank... A 20 gallon tank would work.

If your goldfish is about 2 and a half inches long how big does its tank need to be?
Regardless of the type or size of goldfish the minimum acceptable size of an aquarium for a goldfish is 30 gallons. Buy a tank that is at least 30 gallons if you plan to have goldfish. You can comfortably fit 3 goldfish in a tank this size but no goldfish in a tank any smaller. Goldfish are essentially pond fish and need lots of space to swim; they will not thrive in a small aquarium.
Can an oranda goldfish live in same tank with regular goldfish?
Yes, but your tank size needs to support it. If you mean that a regular goldfish is a long single-tail goldfish, then you need at least a 40 gallon tank just for the 2 fish due to the size potential of the common goldfish. If you mean a regular goldfish as in a round bodied fantail, or perhaps a ryukin, then you need at least a 30 gallon tank for the 2 fish.

How does a goldfish grow as a size of a foot when in seawater and still the same size when in a bowl?
Goldfish release growth-inhibiting hormones into the water they live in: the more goldfish in a smaller space, the less likely they are to grow. For instance, if I have a common goldfish in a 5 gallon tank, it will grow to about the same size if I had 6 of the same fish in a 30 gallon tank. But leave that fish alone in a 30 gallon tank, and it will grow larger. This is why pond goldfish grow bigger. But goldfish won't grow at all in seawater; they aren't saltwater fish.
Have Five gallon tank with two molly fish can you put a goldfish in there?
Wouldn't recommend putting a goldfish in a 5 gallon tank-regardless of what type or size of goldfish. This is because the goldfish would be stunted causing it to have an untimely death. The condition in which a goldfish is "stunted" is where the fish adjusts to its tiny environment so much as to stop growing. The fish will stop growing on the outside but will continue to grow on the inside. Goldfish are naturally messy and create a LOT of waste. This factor would cause the tanks water to be poluted which inturn could kill not only the goldfish but possible your mollies too :(. Two mollies is enough for a five gallon tank. If you truly want to get a goldfish you will have to house the goldfish in a 10-20 gallon tank with very good filtration

Is my goldfish too big for the tank I have a goldfish that is 14cm in a tank that's 30cm long 17cm high and 16cm wide is my tank too small for my fish?
It seems pretty small. You obviously care about your fish so get it a bigger tank anyway. Your fish is nearly half the size of your tank. Answer two- by Neofun Wow. I have three goldfish, not as big as yours, but perhaps the size of an average palm. They live in a twenty gallon tank with a filter, a air stone, and and three other fish. They have live plants, a snail to keep the algae under control, some plastic plants to hide in.
