I have read certain armored catfish and plecos have been kept with Red Bellies. I was wondering is a Feathersail Squeaker Sydondis could be? They are a larger, spiked cat and live with Cichlids in the wild. Thank you.

Back in the eighties I was recognised as the first person to breed red bellied piranhas in captivity. The story was covered in Aquarist and Pondkeeper. If anyone would like to make a documentary on these fish and how they breed I have over four hours of crystal clear recordings which I would be willing to sell. Interested? contact bill_dearman@yahoo.com

Hi I have only 2 red belly's left after they killed the third one. They are beeing very strange : one i half grey half silver and is never calm, he/she is only swimming around and haven't had a break in days. The other one which has bin the most active one is now always calm and never does anything at all. They eat very little and does not Get exited when we feed them. They are also wery jumpy and freaks out when you Get close to the tank. Pleas help me finding a way to save them, i migt gonne have to put them to sleep.

    How old are the Piranhas and how large? if one of your fish is swimming around in a circle constantly and the other is nearby you may have a breeding pair, the male will defend a certain nest area, and may even launch an attack towards you if he feels you are a threat to his nest, but unless your fish are of breeding age this is speculative at best. Also you can search to find piranha's spawning online

    I would not recommend this!  Pirhana are usually species only fish.

    Noooo your tank is a perfect size for a small school of piranhas but the fish you have in it are to large which will lead to problems down the road if your piranha is by its self it will be scared all the time if it is young and die from stress if you get a school of them which that size tank can hold they will team up and slowly kill all of your other fish for protection and if your other fish do survive when the piranhas get larger and need more room they will finish the job from my experience with them the only things I can keep with my piranhas is young guppies and some people have had luck with neon tetras the reason being there to small neons are an expensive experiment is why I haven't bothered I just tank guppies from my other tank when they start over populating the tank and they seem fine when there tiny once they get older though there dead but that's free food vs them killing each others young as would normally happen in a guppie tank when it gets to full

what kind of light colour should be given for red belly piranhas in an aquarium??

    Piranhas aren't adapted for bright light situations and tend to lose their color at night and when they are stressed. The color of the light is not really a factor, they just need a low light environment.

    Curious, what are you feeding the fish?  Any beef products or dog foods?

He he I got a red belly pirahna called Bob had him for almost 6 years now and yeah he skittish lives in a 4 ft tank with a large plec not sure who is more aggressive though the pirahna or the plec but Bob now comes and takes food from my hand. He's the best fish I have kept so far always up to something whether it be trying to hide behind a twig or attack me while I am walking past would recomend red bellies to anyone who has time to watch them :D

    Pirahna make interesting pets, but they are not for everyone.  Experienced owners are a must.

I have a 55 gallon tank and I want aggressive fish. Are Piranha and Pacus basically the same and can live together.

    These fish are from the same family, but are very different.  They do however look a bit similar but that is as far as it goes!  The Pacu grows faster and normally larger in aquariums and is not as aggressive.  They can be very aggressive to smaller fish.  They will eat vegetables as well meat.  Much easier fish to keep, but a 55 Gallon tank will be too small for a for a forever tank.

This is a great article and very well written -- the only thing I would change is when you put the elongatus piranha get a very powerful lower jaw....

I had one for 5 years and even at full size he could barely chunk down anything -- he was tear and rip all his life.

but other than that this article is perfect...Great work!!
