It is angelhair pasta thin. I think it looked more white than clear. It was at night with a plain old flashlight so I am not 100% sure of the color. It looked like it was extending to another piece of rock but retracted when I caught a glimpse of it.
Last night while viewing my tank I saw this white worm like creature 2inches when extended retract back into the rock. It is the only one I have seen in my tank, any ideas? Also just noticed very small flea like creatures swimming around, my guess mysis shrimp. Any ideas? TIA
