The world’s first-ever pink florescent Pterophyllum scalare, commonly known as the angelfish, were showcased in an exhibit on Wednesday prior to the Taiwan International Aquarium Expo, which opens today. Lin Yu-ho, president of Jy Lin Trading Co — the company that cooperated with National Ocean University and Academia Sinica on developing the fish — said this was the first time the world had seen a pink angelfish since the fish was discovered in the Amazon.
