As mentioned, I have an infestation of mysid shrimps all of a sudden. Never use to see these but now I shine the tank with a flash light and they are everywhere.
Here's a small video of a few zipping along the bottom of the sand. It may not look like much to you. But its the first time I've seen them so its pretty neat for me. They scatter pretty quickly after I turned on the smartlite so only a few remain for the video. I don't have a refugium so its amazing that they've survived the large number of predators in my tank and the Aquaclear.
