Thanks for the tip, spent the mourning researching n class Endlers. It appears that mine may be all males, but from my understanding I will never know if n class or hybrid without paperwork.
That's ok was considering purchase of 40g breeder for next project. I believe it will be a colony of blue star n class Endlers and blue velvet shrimp, if my memory is correct on the shrimp breed I liked.
Heavily planted, low population and sponge filtered of course.
