what is this?
 

Hi this was on one of my LR's when I bought it can someone take a guess at what it is? it is about the size of a small pee. The pic is not that good but it is throught a magnifying glass. the brown areas are purple and some floresent green under the attinic. It has little cup like feet sort of greeny yellow in color. also I have some very small hard, white, egg like things on some of my rock and glass I think maybe snale. when they hatch they resemble a clam but nothing left in side.
removed pics.

thank you,
Bill

does the first thing move around or is it stationary?

the second pic is definetly snail egg capsules

1st one looks like a bleached mushroom. Not sure about the 2nd one.

I don't believe that it moves of it own acord, I believe that it will let its self become unatached from an object and then let the curent do the moving. It looks like it has a little hole on its top when it is in a low curent location and lost of light it get little bubbles on top not like a anemone sort of like a fox coral I believe thet are called.
It is very small shaped like a scone or tea bisket. I was prity sure that the second pic was snail eggs but the one that would come up on a net surch were of a glutinous mass with eggs in it. I also have some of these glutinous masses in the tank I am keeping an eye on them. I have boughten 3 different types of snails but have seen about 7 different types now they are almost all grasers there is some tonga snails I believe they only come out when dark or inot shadows. I am not much of an aqua skaper but I do have alot of caves and nooks for fish to swim in and through.

I don't think its a mushroom as it like light but not alot of wter flow it was on a rock with some green star polups in a location that the star polups liked as that is why I got that rock and frag. It looked like it had a bunch of small feet on its bottom but now there is none of them there looks like there is only a single foot now. The lfs guy that sold me the rock gave this guy a squeze before putting the rock in the bag. He shruged his sholders after words. By the way the lfs was on the coast.
As I said it kind of looks like it is scone shaped.
