I don't see any, none on the glass, in the sand, nowhere... but, chances are they're hiding in the shrimp . There was about a 1/2 an hour power out while I was out, and the filter stopped working (thank goodness my siblings took the time to get it working sometime after that), so I'm hoping the lack of water movement and oxygen bubbles killed them.
Its all like your watching your tank with fish in it and all of a sudden the lights go out and when they come back on you see the shrimp rip open and the worms burst out and within seconds the tank is completlely COVERED with them. MWAHAHAHA! Just kidding but woah i even creeped myself out.lol
