You heard him, boys.

On the suggestion of a Fish-related race, three suggestions, related to visuals come to mind, as requested:
The first one is a visual similarly to the Hoshigaki clan from Naruto, humanoids who possess sharp teeth akin to sharks and gills around their body, mostly around cheeks, sides of the neck and sides of the shoulders. They're far more humanoid-looking than the second suggestion. Ex:

Second suggestion would be Zoras from The Legend of Zelda series, which are far less humanoid and more fish-like compared to the above. Basically monster people in similar fashion to maybe Nagas, if that makes sense. Ex:

Third and last would be Mermaids. This comes from pretty much anywhere and is way easier to get playbys, much like the first suggestion. Zoras are highly specific, and very little good playbys come in that style. I have no idea how they would work outside of water, but maybe a small stream of water under them could levitate them to wherever they want to go. Ex:

(For an enlarged version of the pics, right click > view image.)

As for what they could have, they could have a bonus to stats if they take water damage, as if they were refreshed by that water, while also having some resistance to the Water element, and a drawback to another element. (Fire maybe?)

Another cool interaction would be that they would cost less stamina to do the diving mini-game, as they are great swimmers naturally and without the need for oxygen while underwater. Other things could be thought out, so I'm free to suggestions to actually making this race a real thing.

It'd also be great if Mermaids were added as a sub-race to the primary fish race, in similar fashion to Reapers and Apertaurus.
