Help! My red-bellied piranhas are intake respectively other?

There was 4 of them this morning and now there's 3. They are in a roomy 29 gallon reservoir and they are well fed. I'm pretty disappointed because I was attached to them. They enjoy fought before, but its never been this bad to the point where on earth they ate each other. They were all bred from like peas in a pod school so we were told this could never happen. What do I do?
They are probably trying to eliminate the competition. Remember by nature to be precise what predators do.
It's what piranha's do. There is NO way to guarantee they won't kill each other.

They are warfare for territory. They grow to be 12 + inches. Your tank is WAY too small and that's why they are killing respectively other. For 3, you need AT LEAST 75 gallons, preferably 100 +.

To try to stop them from fighting, take them adjectives out, put them in buckets. Re-arrange the whole tank, turn the lights bad and put them back in. Keep the lights off for 1 year.

You need to buy them a bigger tank, or return them. If you keep them surrounded by this tiny 29 gallon tank they will just kill respectively other and you'll have NONE left.

DO NOT SEPARATE THEM. Red bellies need shoals, 3 or more fish. You can't separate them, they wont be merry.

NEVER listen to pet stores, research yourself. Red bellies are way too big for your tiny tank. If your not willing to upgrade your cistern, take them back or give them absent! If you can't take care of these fish, you don't deserve them.

Answers:    a 29 gallon reservoir is roomy for an agelfish or a pair of rams. these cichlids are territorial and dont stray too far from home. in opposition, piranhas, aside from growing up to a foot or more, are like aquatic wildebeests. meaning to read out, they roam around in search of food and other requirements. they do not like to be confined contained by such close quarters. also, fish are constantly searching for food. they'll take a bite when ever one's available. surrounded by a small tank with four piranhas, siblings or not, the most available food is that tail fin flicking around in front of their face. if you watch all those piranha video on you-tube, you'll observe that piranhas almost always attack the tail firs, once the fish is crippled, they shift in for the kill. your small tank is a catastrophe waiting to happen(it's already started). i would advise you to get a BIG tank. as within more than 60 gallons, 100 up if you have the means, later, provide them with some inexpensive playmates/snacks to prevent them from attacking their siblings. some slow moving or erratic-swimming. third, keep them well feed.
capably wait till theres only one and leave it alone surrounded by it's tank. Cause it's only gonna eat the others you put surrounded by with it...you can't predict what fish are going to do, they're FISH...
my mom had 3, next 2, and now she only has one. the one she have she has had for fifteen years tho!! thats pretty amazing to me. eventually, even if singular one makes it, you might want to get a larger tank.
get them ALL seprate tanks, ovously theey are haveing taratory problems, there going to snuff each other to prove who the domite is, your about to lose them all
Why can't fishes live on landscape?   Do you inevitability to ..?   What's the difference between an Aquarium (flat sided tank) to a round fish bowl? ?   What Do Glo Fish Eat? How much should I nurture them?
