The isopod looking things I have in my tank must have a calcerous shell like a snail, hard to explain, but might explain the growth of coralline for camoflauge. I can't see any eye stalks or fleshy foot like a snail or other mollusk. Which is why I think it is some type of isopod.
The "shell" is oval shaped but goes right to the bottom, what I mean is little to no clearance between shell and LR.
I don't know, its not a munnid isopod, in my case. I have tons of them and its not. It is not like the Cirolanid isopod either. It is not transparent at all.
If I see it again I will try to take a pic, but I doubt it will showup. The only distinguishing marks it has from the LR is maybe 3 or 4 white lines that go across the shell, like a rib. That is how I saw it in the first plase. I watched the set of lines move from the bottom of a piece or LR to the top.
I don't expect anyone to be able to identify it by description alone. Just thought someone else might have seen something similar.
Thanks for any responses.....MCF
