I generally like to shake any plants I pluck out before they leave the aquarium. Just to shake off any possible baby shrimp that gets stuck in there. I also leave pruned plants inside tubs of water located in the house. I often find shrimp in there 1 month later, growing and grazing on whatever is in there. I once found a rather large amano in my tub. I'm not sure how the hell I missed a HUGE amano shrimp but... I did. Luckily though, throwing plants away inside a water tub gives them a second chance to be rescued.
Guess I should start doing the same thing. Trying to be safe for the local environment I put any trimmings from my plants in the garbage thinking that they'd be good and dead before the trash gets collected... (I used to flush em...)
