Aeroswarmer

Splitting from its ancestor, the aeroswarmer has begun to absorb hydrogen and funnel it into blimp-like sacs on its back. While it must flap its wings in order to keep itself steady in the air, it can and will float about for hours at a time, filter-feeding on the vast amounts of microscopic species. It can now extend and retract its jaws, giving it a better ability to feed. Young ones will occasionally feed on barnibarbs, sucking them of their juices. They will search for solid surfaces to mate, and males will pump up their hydrogen sacs to their fullest extent in order to attract a potential mate. Large flocks of aeroswarmers fill the skies, though they avoid competition with their cousins by floating at a higher height.

The hydrogen sacs are not yet efficient enough to allow them to float in place for their natural lives, and must flap to keep afloat every once in awhile as well as regulate the amount of hydrogen gas within their sacs in order to control how high or low they float. The sacs do, however, allow them to conserve more energy.

They have become oviparous in order to not get in direct competition with their ancestor, which swarm the flora. They mate every 3 years and have a year long pregnancy, after which they produce dozens of offspring. Females tend to spawn in mass, allowing their young to grow up at the same time and form several new flocks.
