## Customer Reviews

### ⭐⭐⭐⭐⭐ Great Box
*by J***A on January 6, 2025*

I breed platy fish and this box allows the fry to get away from the mother after birth. It does exactly what it is ment to do. It is also very easy to clean when not in use. I have not used the splitter yet but I will when I breed guppies.

### ⭐⭐⭐⭐ Great little box
*by J***D on July 16, 2025*

I bought this as a replacement for another breeder box. This worked get when the snails hatched. I struggled more than I should have to clean the breeder box. So far so good, hoping my stubborn guppy will give birth in this box.
