I have gotten the orange fish since last year October I think? And the gold one since start of this year because I had two but other fish died so I got the gold one :) how can I tell if there age and female or male?

If they are less than a year old, it is difficult to reliably determine sex. Males will be more streamlined than females and, during breeding season, will develop white "dots" (tubercles) on the gill covers. Their vents will also be smaller and more oval shaped. Females will have larger, deeper bodies (for carrying eggs) and their vents will be rounder and more pronounced.
