you guys think it is possible to keep fhs with RBPs? I seen many with oscars but how about a fh?
It is sometimes possible to house aggressive CA with RBP's, but if your keeping a fish for show it makes for a very poor tankmate. Absolute nasty on fins and lips.
I kept a single RBP in a CA community tank in the past, for about 5 years.....my brother did similar as well. I tried it again, 1st with just a single large RBP and then adding a group of 3 that I grew up, making a group a 4......almost 7 years now from when I originally purchased the large RBP; 6 years now for the 2 RBP's I have left, and over 6 years now that my male dovii has lived with RBP.
IME, agressive CA will often push and push......and push until the RBP is forced to fight back. Years ago, in a thread I had, someone refferred to RBP as "bi-polar"

....... sort of true though i prefer to call them "Jeckyl and Hyde". By the way, when they grow up in a cichlid tank, they are not so timid when they get large! Mine have done everything from very poorly to very well, and everything in between.....but for the most part have done O.K. The last number of years aggression from my male dovii has not been too excessive.......aggression usually starts between the 2 RBP and the dovii comes in to assert his dominance. On the other hand, IME, some CA really, really take a dislike to them......I had a couple male salvinis that absolutely hated RBP.
I do not recommend it. And I'm not likely to do this 'combo' ever again. Usually on a cichlid, when a chunk of fin is bitten off, as long as it's ray and not spines, the fin will grow back to it's former outer shape. Though the fin is not really perfect anymore, as the rays are branched with in the fin. With my male dovii, his tail fin is permanently dis-figured. It's been bitten on top of being bitten, after bulleying them in the past. It's very odd shaped now and will never have anything close to a normal shape because of the number of times the tail has been bitten by the RBP over a period of over 6 years.
Never kept RBP with oscars. I've discussed this (cichlids with RBP) a number of times with my brother, who has also kept RBP with aggressive CA.......and were both in agreement, that at least in terms of temperment, oscars are a much better match with RBP, then are aggressive CA.
