From Belgian daily Het Laatste Nieuws:
In China, six tropical fish in a big aquarium in a hotel get much attention from visitors.
The fish do not just kiss each other; they also swim up to the glass to kiss women spectators wearing colourful clothes.
Strangely enough, the fish ignore male visitors.
The hotel has become a real tourist attraction.
These fish are kissing gouramis.
Are the fish all male or female, or both?
Would they kiss (the glass near) the woman on the upper photograph; and not the woman on the lower photograph?
Blue gourami: here.
