Caelapiscus glidus
Descendants of H. limbus, these omnivores have developed large gliding fins as their middle fins reached the point where they were capable of sustaining glides above the water for a short amount of time. The front and back fins act as control surfaces during the glides, and they use this newfound ability to escape H. predata which might attack them and to outcompete H. limbus, who are not as fast as the H. glidus. They feed on more or less the same diet as H. limbus, although will occasionally consume lesser Hexapiscus when food is scarce. They also have slightly altered hunting tactics, utilising their gliding to ambush unsuspecting prey. From head to tail, H. glidus measure around 20cm on average. The eggs have a slightly stronger membrane to prevent them from being eaten, but due to their larger size and new adaptations, they lay smaller clutches, usually between 10 and 20.
