Is there such thing? I've looked on Neocolours, and they don't have it listed on the page for Hydrus pets. I also searched for just a Hydrus Lain. I get this:

So I take it this means there isn't one? Help, please. :/

No. There is not a Hydrus Lain yet.

No problem. If you are ever unsure about pet colors you can do this

and see if an image comes up.

Thanks!
