This is the moment the owner of slender-spined porcupine fish ((Diodon nichthemerus) teases her pets with dried shrimp held with chopsticks through the tank’s glass.
Kousaku Yamaguchi, 25, from Tokyo in Japan shared the video on social media.
The clip shows the fish focusing on the chopsticks and swimming around thinking they are about to get a nice treat.
Besides slender-spined porcupine fish, Kousaku told Clipzilla that he also keeps Cyclichthys orbicularis and Web burrfish.
The slender-spined porcupine fish is one of the smallest members of the porcupinefish family. It has slender yellow spines throughout its body used for defence. This fish has the ability to blow its body so its sharp spines protrude when alarmed.
They are considered shy water creatures that would quickly retreat if approached by divers.
The slender-spined porcupine fish is known to release a toxic substance and are considered poisonous, although they are eaten in some places like Hawaii and Tahiti.
They contain a substance called tetrodotoxin which does not cause harm to them but is fatal to other fish.
To humans, tetrodotoxin is also deadly and is reportedly 1,200 times more toxic than cyanide.
