These showed up almost overnight. I have seen them before in another tank, but not at these population levels. With magnifying glass they look like a shrimp. Shrimp eyes, shrimp legs, shrimp body style. The means of locomotion is very similar to a mosquito larvae. Flexing at lever point to propel short distance. I am attaching photo which of course is not good. Shows body shape only. I have no photographic knowledge. Just selected macro and clicked digital camera (cheap camera too).

Image is imbedded .jpg Just double click the title. Only way I could get it small enough to upload.

If they are what I think they are I collect them in the ocean all the time as food for my fish and inverts. I have a dwarf angler fish that goes crazy for them stalking them and eating them by the mouthful. They get eaten by my larger polyps and all my other fish as well, I have know idea as to species or even genus but they are shrimp and are common around the reefs here in S FL.

definately shrimp

definately shrimp

Thanks for the reply. I spent an hour looking at them through a magnifying glass. They are definately shrimp. Even have little swimming legs. They stay in water column even with current turned off. They just float near surface when no current is on. The also migrate toward light. Congregating near a light placed against the tank wall. I will add some Kent invertebrate food and see if they will keep up their population. My rock flower anemone has been feeding on them all day. It is a very picky eater, so I was happy to see it having a buffet.
