Feathered Fish

In the depths of the Vast Sky, within the viscous clouds rolling underneath the floating islands live many creatures. From magnificent sky whales to the smallest of clowns, feathered fish thrive in the most unlikely of environments.
Many kinds of fish live in the clouds, from the standard fishy fish to squids, octopuses, cloudhorses and the like. In this article, the most common features in all fish are presented.

Basic Information

Anatomy

The bodies of all fish are covered in scale-like feathers that protect them from the moisture in the clouds and help them navigate the viscous currents. Their bones are hollow, allowing for greater buoyancy as well as ease of flight between clouds.
Some fish have softer feathers under their scale-feathers making up wings which they extend outside of the clouds for either gliding to another cloud, or, in the case of herbivorous fish, flying upwards towards the islands.

Genetics and Reproduction

All fish lay eggs. There are many ways they do this.
Some release the eggs into the clouds and let them drift with the currents. Some release them with a coating of goo so they don't drift apart, guarding this packet of eggs with their own life. Some flight-capable fish attach their eggs to the bottoms of the sky islands, which is perhaps the most dangerous as other flight-capable fish, birds, and even cloud folk harvest these eggs as food.

Dietary Needs and Habits

As there is a lack of vegetation within the clouds, most fish are carnivorous. Some flight-capable or adept cloud-jumper (capable of jumping into great heights from the clouds) carnivores go as far as searching for food in the sky islands, sometimes even attacking cloud folk.
There are also herbivorous and omnivorous fish. These are always flight-capable, flying up to the bottoms of the sky islands to nibble on vines and various mosses growing on their undersides.

Perception and Sensory Capabilities

Very little light gets into the clouds, and so almost no fish rely on sight, some having no eyes altogether. Instead, they have pressure sensors that are capable of detecting even the slightest shift within the cloud currents.
