I had bought RES and FHM to stock this pond (fish route truck), and I got a bunch of GSF genes mixed in. It was only supposed to have only FHM and RES in that pond, nothing else as I was raising them to breed and then supplemental stock my other ponds.

I fought GSF genes in that particular pond for a few years.

What are your thoughts on GRES, now that it's been a few years? Still like 'em, or are they not worth the hassle?

Is there a reliable way to sex GSF to ensure I only stocked a female? I've tried looking online & it seems there are sexing guides for just about every other Lepomis species, but not that one. Or should I just play it safe & keep the little green monsters out entirely?
