hmoobvwj: I just got two around 7"-8" from a fellow member on here and is currently housing them with my 7"-8" cichlas
do a little re-examination on this one.........i am pretty certain that the pair has been split.
i kept one from about 12ish inches until it reached about 15ish really fat inches. if you do not have a huge tank ready, look elsewhere for fish. the dorado is not a friendly community fish its whole life. the bigger they get, the meaner they get.
I agree with you on this, It is very aggressive and bully anyone that its size or smaller, since it is a fast swimmer so its quite quick to get away too but will bully. It also aggressive eater and will take food in until its mouth can't close. Mine grown 6" in a month
