hi can someone tell me what these blobs in my fuge are they smaller then a dime and about 1/4 in thick... also i had a mushroom coral that died kept it in tank for about a month afterwords just hoping it was just sleeping and when i pulled it out on the bottom of it where it first started showing problems was one of these blob things maybe a coincidence?

I agree with the pineapple sponge and the 2nd is another sponge. I had one that was the same shape and it was a very slow grower for the year or so that it survived. But it never did any harm to anything in the tank.
 
ok cool thanks i donno if the 2nd one is even alive i reef dipped that green star before dropping in tank donno if it was allready on it...

It's kind of hard to tell from that picture, but it might be a Nudibranch of some sort.
