Homebrew Fishman Species Details

Fish-men have gills near their necks, which only work when they are in water. On land, they can breathe with their lungs like humans do. However, their gills cannot breathe in air, like a normal fish cannot breathe in air through their gills. Even though fish-men are part fish (or at least closer to fish biologically than human) and have been considered such by prejudiced humans in the past, they are still mammals and give birth to live young. Fish-men are also able to modulate the sounds that they make enabling them to speak in the same language as humans, yet at least one fish-man. There are many merfolk who bear physical traits normally unique to fish-men. Even with merfolk and fish-men in the same immediate family, the primary species (merfolk or fish-men), subspecies (type of fish) and appearances may differ. The reason is that they still carry the genes of their ancestors, so the species is not determined only by the parents, but it can be any one type among all the species of the ancestors. Humans, fish-men, and merfolk have the same blood types, and can share if the types match. They are physically ten times as strong as normal humans from birth and this difference is magnified underwater, where a human's power is cut in half, while fish-men not only are completely unhindered, but are even strengthened. Although it becomes weaker on land, and must get wet from time to time. 

Life expectancy- Fishmen reach adulthood at 20 and live up to 100 years old.

While in water, fishermen get additional 2+ STR on top of their initial STR. As they are born in water they get stronger in their natural habitat.
