I am having a blast breeding Blue Dream and Cherry Shrimp in two different 10-gallon tanks. I did have some Cherrys in a 5gal, but I grew concerned with the water parameters and planera. So now I keep a few baby guppies in each 10. On the guppy note, I am currently breeding a ton in a 55 gal. Started in a 20 but they quickly exploded and decided to move them. So, my advice, if you plan on breeding guppies in a 10... be ready to offload them sooner than you think! But many do it to line breed, just be ready 😂 Best of luck!!!
