and cfc what fish would you suggest for a setup with a jardiniI love the gracefull movement and placid nature of the black arowana's and would preffer to keep one over any of the other species but for eye catching striking beauty the jardini's come top of my list, Asians are nice alright but the jardini's with their deep bronze colour with brilliant pink edges to every scale and deep blue tail fins appeal to me more than the high shine Asians.
A jardini would tear a clown knife to bits for fun, they are not even in the same league in the aggression stakes, the golden rule is never keep anything you would be really upset to find ripped to bits one morning with a jardini, or keep them with equally aggressive fish that are more than capable of looking after themselves.
Rays would just end up ripped up and dead.
Just reading every one of your posts about these huge GORGEOUS fish you must have HUGE GORGEOUS tanks. Makes me soooo jealous. haha. Maybe one day. Arrowanas are so beautiful.I have found that to keep aggression down to a minimum the jardini needs to be the largest fish in the tank, but not so much larger that it can prey on its tankmates, tankmates also have to be of the more aggressive disposition rather than peacefull fish that are easily bullied.
I keep my 20" jardini with a 10" dorado, a 8" pike cichlid, a 8" peacock bass, a 10" Cephalosilurus nigricauda, 3 limas ranging between 14 and 10", a couple of large bichirs and a few bits and pieces that hide all day. The jardini is the undisputed ruler of the tank and because all the other fish keep out of its way there is very rarely any aggression, before when i had the jardini in the bigger tank it was constantly fighting with the two 12" peacock bass, my 2 foot Leiarius pictus and large STF because it saw them as competition for territory and didnt want to share.
I cant see how anyone could mix a jardini with a silver arowana unless the jardini was very small and the silver very large, with the difference in build and body shape and the far nastier temperment of the jardini even if the jardini was half the size of the silver the silver would be dead, arowana's do not like each other!!
iver MA has a adult jardini with a adult silver (they are a foot difference in size)and 2 motoros in thier show tank.i have read lots of people having success with a jardini in a community tank.they say if you start the community when all the fish are small and the same sort of size it has a good chance of working.
