I bought a nandopsis beani the other day from my LFS and it beat the crap out of my hole 125. My midas and jack dempsey got murdered? The beani was barely 2 inches, the dempsey and midas was 4-5 inches! How can this little thing murder these larger cichlids in such a big tank? How can I calm down the aggressive pose of this fish? HELP...
 
I have never kept beani but I have read horror stories. The whole nandopsis genus is full of heavy hitters. I know beani are more aggressive than cubans and my cuban male had no problem trying to punk anything in my 125 which included my female midas. These guys are nasty and need their space.
 
beani are best in a species tank cause they are so aggressive. most people who own them rank them as the most aggressive fish theyve had. no way to really to curb a fish thats naturally aggressive. plus being in a species only tank reduces the risk of stress on the beani which could cause them to bloat and die. if you want a community it seems like its really not gonna work with the beani you have. and they are excichlasoma not nandopsis
 
Never kept one but I, too, have read the horror stories. Even people that have kept other aggressive species couldn't believe how nasty Beani are. However, I find it hard to believe that a 2" Beani (no matter how bad ass) murdered a 5" Midas. It just doesn't seem possible even for an Umbee or Dovii... all cichlids are very fragile at such size. It could be that adding the Beani "disrupted the order" of your tank causing the larger fish to start killing each other... this has happened a few times and it's the reason people recommend not to mess with a working community, even removing a single random fish can wreak havoc and result in losses.

I have been keeping cichlids since I was six years old, and that was 24 years ago. I have had my fair share of red devils, oscars, Jack Dempseys, green terrors, and many of the other common “nasty” cichlids that exist in the aquarium trade. Through natural progression I have been fortunate to keep many cichlid species that are quite rare and highly desirable here in the United States. Recently (about a year ago, actually) a good friend sent me a load of these cichlids, which were collected from the Rio Tepic, Mexico. The race of “C.” beani from this river system is quite unique in coloration and pattern, and tends to show a pronounced gold coloration, thus making them a little more desirable. There were 17 juveniles in my shipment, and all measured about 2 cm in total length (TL), except for a big female that measured around 7 cm TL.


There are no words for the aggression that these little cichlids exhibited on one another! Within about a day or two I was left with 13 individuals. I immediately separated them, and it proved to be life saving for many of the remainders. Even still, I was only left with a few more than half of that number by the time I passed them on to a good friend of mine for his collection. Based on my experience, I strongly believe that Sonoran cichlids need to be kept in a single-specimen aquarium. All other fishes are in extreme danger of being murdered if housed with them!

WOW! :WHOA: Well I currently have a 4" Beani in my large show tank. He shares it with a Bleekeri(yes a Bleekeri), 2 Hon. Jags, and a Grammode female of equal size, and also with Hoga 11", loisellei 11", Kraussi 12", Devil 10", Grammode 9", Uropthalmus 9", Lenticulata Pike 9", and a few stragglers around 6-7". So far the Beani keeps to him self, and doesnt even bother the smaller fish, in fact he hangs in the same cave as one of my Jags.

Dont get me wrong, I am not saying that Beani are peaceful, and that you all are smoking crack. :) Im just saying that it is working for me so far. And strongly agree with cacichlids about your Beani being the one to do all the damage.

Yeah, you were right. I went out and bought a convict and it wasn't the beani who was murderous. I just think the dempsey and the midas got tired of each other. The convict and the beani swim together and have no problem. Great fish, but there are way to many myths about them.

No way a little 2 inch beani could take out a 5 inch midas. :screwy:
Pathetic, pay close attention of what is going on.:duh:
