Couple Of Ids And Questions

[Demm]

well stuff is starting to really grow in my tank alot, most of the stuff i'm clueless on. so im trying to find out what stuff is

sponge i'm guessing?

my guess to these would be featherdusters, they are white little worms, but they have a little feather thing on one end. i have alot of these that are just laying on some of my live rock.

what are these red spots on the back of my glass, is it red algae? bad?

ok this i was not able to get a good picture of at all. it looks like a tiny clam or something, my friend said it looks like a seed. it just sorta showed up outta no where and hasnt moved, what is it? (again in this picture you see one of those white worms)

thanks for the replies

red spots are probably coraline. Good, it means your tank is becoming more stable and calcium levels are good. You can keep those spots and watch them grow.

Sponge/tunicate of some sort, mini featherdusters, coraline algae, and the last pic's a little too blurry to tell

Sounds like a clam bivalve of some kind. Filter feeders stick him on a bit of rock and hell move into a good position for feeding.

awesome thanks for the replies

the clam thingy is gone, i guess it went to a better spot to feed or something, if i see it out again then i will try to get a better picture, i dont wanna go in there looking for it, especially if it's not hurting anything.
