Woo hoo I saw a shrimplet in my shrimp/guppy/neon tank. it was on a seed pod for a plant I am trying to get to grow (but probably won't) the other night and then I hadn't seen it for a day or two. Well yesterday I was doing my weekly water change/snail vacuuming (I use the tank vac to suck up as many pond snails as I can.) and almost vacuumed the little guy up (saw him in the tube and released suction). This little guy is about 3 millimeters long.
