Okay...
So after our first attempt went well, the professor at the university was so excited by the early footage of spawning and fry that she wants more. In fact, we got to talking double-tails and she was curious to see what would happen if we combined those genes with that of a crown tail.
You've probably all seen the pictures Starving_Poet posted of Ariel a couple months ago: the pretty blue double tail (either super-delta or half moon...really not sure which) with the white butterfly...he's the custodial parent for this project.
The female we have in mind is a very dark bodied (almost black) crown tail with purple iridescence and fins.
We know the finnage in the offspring is going to be messy, but nobody is going to care about that where these guys will be going.
Hopefully this works out. We currently have Hermione floating in the chimney, being acclimated to the water. It took him a while, but Ariel has finally realized that there's something moving in the container floating in the big glass object in his tank.
