Mike, you are fully right in saying that we normally look for the males and do not do the same for the females. Yes, this is a mistake. One of the consequences is that we are very bad in recognizing female licorice gouramis. They seem to look more or less the same, but that is wrong. Admittedly, they are much more difficult to be differentiated from one another, but at least in about half of the species it is possible. Still more interesting is the female behaviour in display and courtship. So your video is a valuable help in correcting our modes of looking at these fish.
Thank you!
