The first picture, *might* be Bryopsis...although I could be wrong, I don't know what kind of snail that is in the second pic...the third picture looks like a mysis shrimp, the last looks like a spaghetti worm.

Those are my best guesses!

Does the snail have a little pecker sticking out of him if so he is a nassarius (good snails)
The alage lookes like it has small feathers on the ends if so Feather Calupera (Good for a fuge)
the one is just a little shrimp (good)
The other Looks like a little Spaghetti worm (good)

You have alot of good things going on in your tank ;D

pic 1. Bryopsis...remove now before you have a big problem. lettuce nudibranchs eat it or if you can remove the entire rock or area of rock without breaking the algae up.
pic 2. looks to be a nerite snail.. probably safe, but you may want to remove just in case
pic 3. amphipod. perfertly harmless and beneficial
pic 4. sphagetti worm. harmless scavenger

thank you everyone for your help. I just get rid of Bryopsis and clean my tank with scrapper since I see a lot of these little green algea on the backwall of my tank. What Should I do in order to control the green algea? I hear that green algea is unavoidable. Am I wrong? I have four Koralia 4 in my tank. Is it enough of water flow to control algea growth? My tank size is 125 gallons

I guess I need to buy some fish that eat this algea.

On the snail -

Look up either Heliacus Areola (EVIL)

or

Collonista (mini-Good guys).

They look really similar to one another so it'll be tough to tell. Snail identification is notoriously difficult unless you have a phD in invertebrate zoology (a la dr. ron shimek). Even then he scolds us for not posting pics of the snail operculum/lid/opening.

1,4,&5 look like aptasia anemonies....bad fast reproducers and will take over if given time
2 looks like a type of sponge (cant remember name at the moment)....not a problem
3 look like some type of pods but hard to tell from the pics....not a problem

 

[Olivier]

ah sh#t.  I bought these rock from a member (Jabis96). Now i am going to throw these rock out.
thank you for replying my post and help in ID these thing.

Update:  I took 3 pieces of rock (From Jabis96) out of my refugium and deep it into fresh water for 3 weeks to kill everything on the rock.

Do I need to do anything with my refugium since the Aptasia anemonies was in the refugium before specially there is one of aptasia attach to the wall of my refugium?

 

[albie611]

no need to nuke the fuge. just scrape it off and remove it
some people have had sucsess using calk paste or joes juice to get rid of aptasia...
there should be lots of info on it somewhere in the forums or rc's forums
good luck.......al

That third picture looks like Hydroids, I had them in my fuge at one point, but they went away after awhile.

That third picture looks like Hydroids...

That's what I was thinking.

 

[Olivier]

Brian and John,
Hydroids a good thing to have or bad?

 

[JohnS_323]

I've always heard that they were bad but if Brian's disappeared without incident, I could be wrong.

 

[Brian]

I've heard they can be bad, but I had...I dunno...hundreds of them and then one day.. *BAM* they were gone.

I don't know a whole lot about them though...I believe Panmanmatt was the one who told me what they were originally.
