I recently had the pleasure of acquiring a bunch of neos! How does one best go about vacuuming a tank full of tiny shrimp? I moved things around in the tank today and they didn’t seem to get out of the way. I am worried about them getting vacuumed up when I clean the tank. Previously I put panty hose over the vacuum to avoid sucking up fry, but that prevents me from cleaning out dead plant matter and the like. Any suggestions?
