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.

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!-)
