Chandos fish

These omnivorous fish often had a long, slender body and a thick spine running down each vertebra. Typically, their scales were either white or a dark golden tint. They have the capacity to use bioluminescence to produce their own illumination. Even though they were found in other worlds' deepest oceans, these fish were exclusive to the oceans of Chandos. The Chandos fish were always hungry and were always looking for food to feed their stomachs. They weren't picky eaters, but they did prefer freshly killed meat to flesh that had been sitting about, and they preferred old meat to the algae, sponges, fungi, and other marine plants that lived in the Chandos oceans.

Combat
When Chandos fish discovered a potential food source for recently slain meat, they attacked it right away. When the prey was killed, they didn't wait to eat; instead, they bit with the intention of removing and devouring that chewed piece of flesh. When a feeding frenzy breaks out, more damage is inflicted on the enemy as a result of this attack form. The fish quickly went into a frenzied state akin to that of a barracuda or piranha once they smelled or tasted blood. All open wounds were targeted as they flocked to the areas with the most blood. During this frenetic attacking, these fish frequently engaged in intraspecific aggression.

Habitat/Society
When they were young, chantos fish typically grouped together in schools. This guaranteed both their mutual training in survival and their own survival. They became alone until it was time to mate after they were big enough to take care of themselves. The territorial impulses that several animals have were absent in Chandos fish. If the prey was too small for more than one fish to eat in a single meal, they protected their food. These fish put their eggs in strings that could be up to 50 feet long and contained more than 1.000 eggs each. The eggs were placed in the holes and fissures of rocks. Not every egg hatched, and not every fishling survived to adulthood. Only around 12 of the 1,000 eggs laid by one adult lived long enough to reproduce. These fish had a three-year average lifespan, with the breeding age falling between six and eight months. These fish were very loyal to their partners who had been pregnant. The male swam at the female's side until she lay her eggs, guarding her from any threat, real or imagined. Once the eggs were laid, they were never again united. They don't mate again; instead, they each find someone else when the time is right.
