Arimen
The Arimen are a species of bountiful and beautiful sea-fish which travel in large shoals.
Basic Information
Anatomy
Arimen are relatively small fish with miniscule, entirely black eyes.
Genetics and Reproduction
During the reproductive season, female Arimen spew their eggs as they swim, and male Arimen spew their sperm. The two mix as they fall, and the sperm mixes with the egg coating to make the eggs sticky. These eggs then attach to Arimen as they fall, where they spend the next week or so gestating before the goo dissolves completely and the eggs fall off the adult fish, only to be split open when they hit another fish, and the fry escapes the confines of the egg.
Dietary Needs and Habits
Arimen consume plankton.
Additional Information
Social Structure
Arimen shoal their entire lives, swimming through the ocean in vast groups that can span many tahm. The shoals seem to have no defined leader, and individual shoals will stop merging with others once they reach a certain size, instead depending on reproduction within the shoal in order to expand.
Domestication
Arimen are sometimes caught and kept as aquatic pets, but they often die quickly as very few possess (or wish to waste) enough wealth to keep enough Arimen that they don't die of loneliness, and to provide enough space that they don't die of boredom.
Uses, Products & Exploitation
Arimen, though small, are the main source of aquatic meat, due to the fact that their large shoals are so easy to fish in using nets, and that the shoals are so ubiquitous. One fish generally produces a little less than half its weight in edible meat.
Perception and Sensory Capabilities
The Arimen forms shoals and moves in schools based on the type and amount of pheromones it senses from its neighbors, and thus relies heavily on pheromone-sensing and -producing organs.
The diminutive eyes of Arimen are rod achromatopsic, meaning that the fish can only see objects in shades of gray, and find it more difficult to see in brightly lit areas.

Body Tint, Colouring and Marking
The bottom half of all Arimen is a light to mid-tint blue, and the top half can be any of a wide variety of colors. Top-color is determined by the unique pheromone mix that each shoal gives off; thus, all members of a shoal have the same top-color, with the exception of recently merged shoals— these would have two or more top-colors until the pheromones had been evenly distributed.
