Last night while checking on my yellow shrimp, I noticed about 4 of these:
I have absolutely no idea what they are. I've had no fish or otherwise in this tank, just my shrimp and the invading population of snails. I have java moss, which I got from two places: my lfs and the breeder of my yellow shrimp. The moss from the breeder is also in two other tanks, and no sign of these guys.
At the lfs, I *think* there were madagascar rainbows, possibly others, in the tank the moss came from. Who knows what else was there before.
I also collected shale/rocks from the creek where I live. Seems a bit cold for anything to have survived though, and I did wash the stones thoroughly. And since fish don't grow on trees, I'm not worried about them coming from the leaves in my tank.
As you can see from the picture, they're basically traingles with heads

. They seem to have 3 blue/black stripes running horizontally at the top, middle, and near the bottom of their body.
I have to admit that I haven't looked into what these could be too much, but I just thought I'd go ahead and ask here. Thanks
