I'm going to send a few hundred to a big shrimp bro for store credit when it cools down. Hopefully he will be happy with semi-grown out fry or else that many will take a full sized fish box. I need to get into the pond and get an idea of how many I'm looking at in there. There were thousands last time I did it using about 50 adults, so I only put about 10-12 females and the nicest males this spring. But they roll the water surface when I feed, so I'm thinking it's still more than I can deal with. Next time I'll try 5 females. I wouldn't think the first batch of fry has grown and is reproducing already, but who knows?
Nothing good happens fast in an ecosystem.
