a few easy id's please

[dangalla]

tank is a 55 standard with 260watt pc, about 3 years old
first one is some type of algae i believe, its kinda cool looking i guess so i dont really mind it as long as its not hurting anything


the next one i am really not sure of, prolly algae


and the next one is the one i am worried about, its like some kind of tube thing that seems to be made out of sand, it has "hair" or tenticles around the top and if anything touches it it retracts into a ball thing. i have them all over the place and they are worse in the sand. there "tube" goes pretty deep into the sand also

thanks for the help, i really appreciate it alot

1 - red macro algae - not bad
2 - red slime algae - nuisance
3 - feather dusters - filter feeders - tube worms

I'm thinkin' 2 is a kelp or other red algea. Can you get a better close up.

2 looks like Cyanobacteria - aka red slime algae

If 2 has air bubbles and can be siphoned off its cyano IMO. It could just be a dark red coralline algae or a red sponge.

#2 is not cyno, it looks like small leaves. i will try to get a better pic
#3 is not a macro feather i have a bunch of them, its not really a worm the "tube" is actually part of it. and the tenticles look more like a anenome, but i am pretty sure its not apstatia

 

[dangalla]

here is some more pics of #2



and i cant really get a better close up of #3 but here is another pic of a group of them next to a small snail. the center seems to be greenish in color ant the tube is clear with sand all covering it

again, thanks for the help

If you see a little perescope thing sticking out of the sand its a nausarius (spelling?) rght when i put mine in they burroewed in the sand

I am pretty sure that #3 is not a snail but is some type of tube anemone. I tried to do a search and did not come up with much.

I really can't see it in the photo, but I'd bet that it's a scavenging worm of some kind - ie spaghetti worm, etc.

when it retracts its not like any tube worm i have ever seen, the "center" does not go inside the "tube" it just kinda goes into a ball. also they dont seem to bother any of the hermit crabs or snails when they do touch them, they just retract. i will try to get some better pics tonight
if you click on this pic to make it larger you can see a bunch of them in the top left corner

and in this pic when you click on it again to make it larger you can see it best

Ohh I have those in my tank also
