Taiwan Goldfish

Scientific name
Macropodus opercularis
English name
Paradise fish

Features

This small fish, about 7-8 cm long, lives in ponds and rice paddies. It is also found in the Ryukyu Islands and other areas of Japan. When breeding, the male first makes a foam nest on the surface of the water and welcomes the female. The female then lays eggs in the nest, which the male guards. During this time, there may be fierce fights with other males.

From the breeding staff

Due to their aggressive temperament, they are also known as "fighting fish." The sight of them spreading their fins and threatening each other is very beautiful, but the fish themselves are desperate.

Papuan jellyfish

Scientific name
Mastigias papua
English name
Papuan jellyfish

Features

It has eight sponge-like oral arms under its umbrella, with appendages at the end that resemble the legs of an octopus. It mainly lives in calm bays in warm ocean waters. It lives symbiotically with zooxanthellae inside its body, and obtains energy through photosynthesis. It is not highly toxic, but may be painful to touch.

From the breeding staff

The white polka dots on the cap contain calcium carbonate (a component of Corals skeletons and chicken eggs).
It is thought that this is to increase the strength of the umbrella, but the details have not yet been clarified.
Please try observing it and comparing it with other jellyfish!
