    Hey APU,

    Why has no one bred the Black Rhom Yet???

    I search everyday too find the answer but OPEFE has about the only answer that makes sence...maybee they release a fairmone that calms them before spawning so they dont shred each other

    If you check this OPEFE linc halfway down it explains...


    What Is The Reason Rhoms Can't Be Bred In Captivity???

    email when replied,..very interesting,..have read another article
    with a brief reference to 2 successful accounts of breeding S.Rhombeus
    in captivity,..very interested to hear if this author has a link
    to share with more detail or better yet a personal account,..

    Wonder how many Rohms He went through to figure this article out?? I have my 125 gal divided and there isn't a day that goes by where they don't try to kill each other!

    I don't believe that you can breed rhombeus in 100g tank. unless you already have a breeding pair paired up and just move them to a 100g tank for nesting purpose.
    first you'll need enough number of rhombeuse to increase the chance of having enough male and female to form breeding pair(s), second as we all know that rhoms needs to be kept solo in home aquarium unless the tank is big enough for them to each have their own territories without killing each other, which most of us won't be able to provide that amount of space at home dedicated to just a few piranahs. when you put these two reasons together you'll be nearly impossible to breed rhombeus in captivity. even if you do get a pair of male and female together there's no guarantee that they will pair up and breed. The only one case that I can remember was a breeding colony of rhombeus were found in abandoned pond/pool in Florida, if remember correctly it's like over 1000g. I think I read it some where on www.opefe.com

    here's the link www.opefe.com/rhombeus.html

    "RELEASED AS A NON-NATIVE

    S. rhombeus has the dubious distinction (along with Pygocentrus nattereri) of being the only two species of piranha introduced in Unites States waters. In Florida (1977), a breeding population was discovered at an abandoned amusement park (originally misidentified as S. humeralis) in Dade County. They were found in an over 1,000 gallon outdoor pond where they reproduced. Even more interesting, the fish survived during Florida's winter. Preserved specimens from the Miami area were deposited at University of Florida UF 87975, UF 97059 ) and were determined by W. L. Fink University of Michigan [personal communication between Leo Nico Florida DNR and W. L. Fink, Voucher specimens: Florida to be S. rhombeus and not S. humeralis."

    besides, even you do have a tank/pond big enough you may not want to waste all those cash on buying large size rhoms(so that can be sure they are full matured and ready to breed) and have a great chance that they will kill each other.

    All the info is soooo interesting...I think answer to metals question is one......One must have a huge tank(zoo size) in my opinion bc we all know any p's are territorial and depending on what they are how territorial they are.the more room the better. It also mentioned breeding was successful twice but simply put with alot of death in the proccess.I think bc of lack of territory. But also soen in research has been in huge tanks and nothing.Intersting though how humans have studied them for so long and still do not have not nearley all questions answered.Perhaps they are shy! Who knows.That my fellow p lovers is why I love them so and continue to learn. but all this is just my opinion.And also is why I work with animals and not people!

    My way of thinking about this question is that the classification-issues within the rhombeus-complex as whole, may be the actual reason for unsuccessful breading attempts.
    The great morphological variations within the complex may keep the individuals from recognizing each other as these variations may be seen as strange signals for one or both fish in the tank.

    Besides, when comparing with the breeding-behavior of S. marginatus, that is ca 22 cm when adult and requires roughly two square meters for personal territory, it easily estimated that an adult S. rhombues may demand at least 5 square meters of it's own to be able to accept con specific individuals around it once it has started nesting, if a 100% certainty of non con specific aggression is the culprit.
