I saw an australian arowana at a lfs. it was about 4" and wanted to know the care of these fish: how big they get, water chemistry, foods all that good stuff. anyways i am interesed in buying it but the people at the lfs didn't give me alot of info. also i heard they were quite a bit more aggresive than silvers. if this is true, can i keep it with 2" frontosas. any info will be appreciated.
