What size fish tank should two piranhas be in?

Question

It would help if u told me wat species of piranha your talking about when you te.ll me the tank size

Answer 1

There many types of piranhas but let's say Pygocentrus nattereri, red-bellied piranhas, which tend to be most common are not an exorbant size.
First, though, piranhas are schoolers, and should not be groups smaller than 5 fish. 100 gallons would be the recommended size tank for 5 adult piranhas. However, they can be kept in a 50 gallon tank until they are about 3 inches each.

Answer 2

Hello-

I raised piranhas (red bellies) twice from tiny babies to full grown Monsters (About 1/2 and inch in length at birth, to around 6inchs once full grown). I've also helped friends do the same several times.

I did the same thing both times which seemed to work out just fine. To start (7 babies) place them in a 20 gallon tank then once they reached a length of about 2 inches I put them in the "Full grown tank" mine was a weird size of 48 gallons. They never seemed to be scrunched or at a loss for space.

There was a short period of time when I had full grown piranhas in a 30 gallon. That seemed a little bit short of space so the 48 was more right in line with "a good size."

I think that the standard 55 gallon tank with it's wide body would have been kind of a cadillac of tanks for them. Anything higher probably would have been overkill.

In your situation however, we're talking about 2 piranhas. 30 gallons might be just barely too small and the 48 gallon like I had is probably more of a luxury tank. If you can try to look around for a tank within those 2 sizes (I'd say a standard 40 gal size) your piranhas will live a good life.

For the most part, the piranhas will remain docile and they pretty much like to find places to hide on the bottom. However, once startled they can really disrupt a lot of decoration and filtration systems in the tank. In a small tank they'll dart across the bottom in the blink of an eye and slam into the glass on the other side.

Answer 3

I don't think Piranhas should be in the same tank, they need to be separated.

Answer 4

hmm, I swore I answered this already.

55 gallon tank at minimum.

Don't listen to the people that say 1" per gallon. This is a false rule and will only get you in trouble.

Answer 5

There is an old guideline that says allow one gallon for every inch (in length) of fish. A ten gallon tank would be fine for two up to 5 inches in length each - pretty good size!

Answer 6

a tank the size of your living room

Answer 7

Do you live in the United States? I thought piranhas were illegal here?

Answer 8

half gallon. Make sure you put a tight lid on that so when you throw the kitten in the bowl, it won't be able to get out and also, it'll keep the blood from splattering everywhere.

Answer 9

55 Gallon or bigger. )O(
