So I just started with the hobby and been reading a lot in the forums to be a better keeper for my natts. I’m just wondering is there a timeframe to when ur supposed to introduce additional fish to the group If u decide to? or can u like for example add more fish to a group of natts who grew up together for like a year Wether it is a the same species or not. Ex adding 3 caribe to 3 natts who are grown up. Thanks in advance guys
