Hoopfish

The Hoopfish is a common, passive fauna species that can be found in many biomes.

The Hoopfish is fairly easy to catch, as it doesn't retreat upon being approached by the player, and is easily recognized due to its bright bioluminescent glows.

Cooked Hoopfish have moderate Food properties.

Appearance

The Hoopfish has a slim build, featuring a dark violet colored body that gradually transitions into blue towards the head, which has a bright neon green color. It has two green eyes, a small dorsal fin and a purple caudal fin that wraps around its end.

The Hoopfish's most distinct feature is the bright green bioluminescent antennae extending from the top and bottom of its head and bends around its tail forming a hoop.

Behavior

The Hoopfish is a rather slow swimmer, and is mostly seen forming shoals in various biomes. It would often try to flee if approached by the player.

Hoopfish are commonly seen grouping up around Reefback Leviathans in groups of 3 to 4.

Data Bank Entry

Small, school-mentality prey fish with a unique method of propulsion, and a distant relative of the bladderfish. 1. Antennae: Rather than swimming, this lifeform uses the fine green antennae which encircle its body to alter the composition of the water in front of it, allowing it to 'sail' into the low density space created. 2. Purple/Green Coloration: May be a camouflage adaptation for mid-range light wavelengths, possibly indicating the hoopfish is more active at dawn and dusk. 3. Behavior: While schools of hoopfish will form periodically and evade predators en masse, this behavior is more social than it is defensive, and lone hoopfish are often found hunting for food and displaying generally curious behavior.

Trivia

• There is a subspecies of the Hoopfish called the Spinefish that dwells exclusively in the Blood Kelp Zone and in the Lost River.
• The Data Bank Entry for the Hoopfish states that it changes the composition of the water in front of it to propel itself through the water. In spite of this, the Hoopfish ingame still pumps its tail like a normal fish when it moves.
• Judging by the tooltip for Cooked Hoopfish, their antennae are likely poisonous (or at least not very tasty).
