Horsea are always known by being sensitive to their surroundings. If they sense trouble, they spit ink towards the instigator and flee. Horsea also spit ink to shoot down flying bugs for food, using their tail to keep their balance. When they are a safe location, they can be seen playfully tangling their tails together. Horsea do like swimming around, making them adept at using their fin. If the ocean current turns fast, however, Horsea will anchor themselves by wrapping their tail around rocks or coral to prevent being washed away. Horsea are also known for creating many nests at different coral reefs in the sea.
