Piscon

 were a species that were related to the Pescatons.

They resembled angelfish with deep black strips over their heads and fins.

They were originally humanoid but a war with the Schienox changed their evolution pattern. They also had the capability of making Humans immortal but at the cost of turning them into a Piscon. (PROSE: The Time of Piscos)

The sun of Piscos exploded turning the Piscon home world into a desert world. They went round the universe finding sources of water, mostly from uninhabited worlds, but some such as Zarl took it from inhabited worlds, like the Earth. (AUDIO: Peri and the Piscon Paradox)
