A fish species i designed for some kind of homebrew DnD campaign i'm planning. They're called pesci and coexist with some humans in a coastal town the heroes will be stuck in. Their skin and scale colours vary between different hues of blue, brown and green. They only survive a few minutes on land and are nearly immobile. They keep living in the sea hunting fish and farming kelp and corals. They only visit the coastline and the canals of the town to trade with the humans.
