well they were about 4 inches when i got them last year in june , so i guess about 9 inches .
there known to be a little slower growers then say , silver arowanas or peacock bass or something like that . which i know from my own experience .
in my mind its a good thing as it buys a little more time before needing a huge tank .
i suppose i could have maybe got them to grow a little quicker if i had of power fed them a little more . they are fed pretty good though so i think its just that they may be a little slower growers then some of the other big fish that are more commonly kept
