A fish that sleeps on its side?
For November 2026, Danuri Aquarium chose the giant mottled eel as its fish of the month. Its official introduction describes the eel resting on its side. A motionless fish is an invitation to learn about its behavior rather than immediately assuming it is unwell.
A large eel
According to Danyang County, this species can grow up to around two metres long and occurs in regions including Jeju Island and Southeast Asia. Not every individual grows that large or always rests in the same posture. Children can compare its body and movements with those of other freshwater species.
Where to look
The November feature points to a display on basement level 2. Live exhibits can change for animal care and operations. Do not tap the tank or disturb animals, and follow signs and staff guidance.
Before you go
Danuri Aquarium is a freshwater attraction in the Danuri Center at 111 Subyeon-ro, Danyang-eup, Danyang-gun, North Chungcheong Province. Standard official guidance lists 9 AM–6 PM Tuesday through Sunday, ticket sales until 5 PM and normal Monday closures. Holiday Mondays and major holidays have exceptions. Confirm today's opening, prices and transport details before leaving.
Taking time to observe one species can turn a family aquarium visit into an introduction to river ecology.
