These things are all over my sump. It is weird, because the water is filtered through a 100 micron filter sock before entering the sump.
Is it possible it's snail larvae? I do have tons of snails.
I keep a large hermit crab in the sump (since he made a habit of eating said snails).
They look like grains of white rice, but as you can see in the picture, some of them appear to have a head-like section that splits in two.
Anyone know what it is?
