What’s the most fun fish/invertebrate that you have ever bred and why?

Hey all! 
I’m currently towards the end of my small expansion to my small fish room for breeding. I’m getting into it for fun, and a way to support the hobby. I’m currently breeding red tuxedo koi guppies, red cherry shrimp, and sterbai Corys. 
 

What’s the most fun/ rewarding fish or invertebrate that you have ever bred? I’m curious about the responses.

That's a great combo!

Platties and Plecos for me I guess.
