Choosing an arowana

I think jardini are the toughest out of them silvers and blacks , but there also the most aggressive so tank mates will be a gamble , blacks ate very fragile when young and nearly all silvers end up with drop eye , as for jumpiness there all jumpy when young but most soon grow out of it with human contact (people walking past tank spooking etc ), you'll need a tight fit heavy lid for any aro as they all jump

I've kept blacks, silvers, and leis and noticed that blacks jump the least. I still have all tight lids on my tanks though. I also noticed that blacks take a longer time to be comfortable with you walking up to the tank and feeding etc. They are also slower growers than all the other arowanas.

So my question is of the arowana species legal in the U.S. which is the most hardiest species and the one least prone to health problems. I have also read that the species differ in how "jumpy" they are. Anyone help is very much appreciated.

Lei, or jardini I'd say would best fit the description your looking for. Silvers get DE. And african arowanas if I'm assuming corectly are filter feeders so it can sometimes be hard to get them eating. Blacks are just a lot of money for nothing extra. They end up looking very similiar to silvers once full grown anyway imo.

from what ive read afrowana feed like any other after about 8 inch then become very hardy and are the least jumpy and least aggressive, best for a comm. unless someone can correct me thats the best for you imo. only downside is finding a larger one could be difficult, as said very hard to get eating when small hence fragile. i wouldnt even consider silver again, asthetically once it does get de which it will it ruins the fish, best left to the amazon!-)

Jardinis get great contours on the body shape after 18 inches but lechartdti have some nice red fins when the get larger and they seem to hit the 24 inch mark more readily.

Afro are nearly as aggressive as a jar when they got big

Leis need a wider tank than a jar when full grown. Keep that in mind unless your going with a 600+ gal tank where it prob won't matter
