Welp, here's your species, casey!
-I know you said you wanted a water themed species; I hope a fish-themed
one is okay, though. o//v//o
(This is really not creative at all, but I was tired -v-)
Anyways, this species is based off of an angelfish. They have two fins; a tail fin and
a dorsal fin. -Plus those two long string thingies that are always on angelfish.
They have brightly colored spots/scales. They're often seen with small starfish
clinging to them, as well.
I'm not too crazy about these lines at all, but I hope they're easy enough for you to color. ^^"
