Can't you drop blanched vegetable in one corner, let them swarm it, then hit the free substrate like a woman possessed, then move said vegetable to hit the remaining corner? I never had shrimp long enough to get shrimplets so wouldn't know personally, just an idea you can correct me on lolNowt wrong with that. My apologies, I'm picturing you as a male clown now, so I won't get it wrong in future Also congrats on the new shrimp! My current method of letting buckets settle then checking for movement usually works and doesn't take hours, so give that a shot in the meantime. But it would be great if anyone has developed some better techniques for really making sure.
