Aqua

I was thinking about a name for her... Hydra came up as a name or part of it, but then I figured a Hydra is also a multiheaded beast, so that would be a bad idea.... Aqualady is the name I gave her on my computer... Can any of you guys think of a pretty name for this water creature???
This started on a sketchpaper as an idea of how a human face might look like adapted to the water. A soft dolphin-like skin, pretty colours, the more aerodynamic shape... This is the A-4 version of that sketch worked out in colour. I hope you all like it. I myself am quite satisfied with the result. I was afraid to screw it up by using the colours wrong, but I didn't damage the drawing to much. Done with Bruynzeel colouringpencils. All in all it took me about 4 hours to make. I was very carefull not to do too much colouring at one time and used a lot of layers to get the right colours and transfers.
So anybody??? Names??? I'll pick out the best suitable one and she will be known by that name.

EDIT: So, I looked up some names in the fishy encyclopedia and found a few names being:
Poecilia (witch is part of the BIG name for a Guppi)
Daffodil
and Telmatherina (wich isn't the pretiest of the three, but it is a colourfull fish)

So I was thinking about one of the first two.... Or maybe some of you have other (better) ideas??
