I know rhombeus are a solitary species, but what about keeping them in an obviously large tank with piranhas but seperated with a divider? Would that cause a problem or is it ok? It is something I'd like to do in the near future.

arrow;4303736; said:It will work as long as the divider is secure but I would advise against it.
Either of the fish may get stressed(most likely the rhom) and not thrive as it would with the whole tank to itself.
How large of a tank were you thinking?
3-4 reds would need atleast a 75gal 4ftx18in to thrive and a rhom at least 3ft depending on how big it is. You would need a minimum of a 6ft 125gal to do this and even that would not do for the life of both species.
I would focus my energy on either one or the other, keep em right or dont keep em at all.
Good luck with that and let us know how it goestman;4304444; said:Don't try this at home!! LOL I currently doing an experiment. It worked for me about 12yrs ago... I put 2 rhoms and 4 red belly in the same tank and they coexisted for about a year until I got bored of them and sold them. Now I am trying it again with bigger fish and I currently have 6 6" Red belly with 2 diamond rhoms(6" and 8"). I started it on July 14th and so far so good. Just couple bit fins as they were establishing their territories. I wouldn't suggest trying this as it can go South pretty fast and you would have to have another tank available just in case.
