Well when I give advise I speak in terms of the fishes lifetime because when I buy a fish I make sure what I have can hold it for its lifetime, if the op doesn't have the intentions of keeping the fish through its life then by all means go for it. But he didn't state that, so I will give him advise based on the fishes potential. Same way I did for you, you plan on keeping your aimara for life, I told you what I feel is ok for life, you asked about 8x3 I believe, in which case I'd say yes you can keep it for a number of years, but for life no, it will need more width. And we can't say no one has grown the fish here, cause there are plenty of people who might not even know of the forum, or don't have an account just come up here to read and not report. I stalked this website for years before making an account. The specimens in Asia that have been grown to that size show that it is very possible, so I give info based on the potential of a fish is all
