[merlin21k]

I know this is not a very good pic but if u can see i have these small white objects on my rock. They look like little white pods. They dont move either and i just started to notice them. Any help??

Theyre probably tiny feather dusters, I get them on my glass. HTH

I have a guess that they are possibly Scypha sponge, look at this:

Yep, Scypha sponge.

Pineapple sponge. It is a good sign of water quality. They are filter feeders and no need to worry about them. They usually hang in areas with no light and good flow, like in overflows.

By a good sign of water quality, do you mean a sign of GOOD water quality or bad water quality? I've got these guys all over the place. :huh

Good water quality = LR biodiversity.

Bad water quality = nothing growing on LR except maybe nuisance algae).
