Identify plz

[OceanCrazy]

I noticed these pinkish organisms on my live rock, at first i thought they were some kind of worm when they were tiny but they are growing and looking like an anemone.Any idea what it is?

Looks like a ball anemone to me :) I have plenty of those. Harmless, I think.

Is it true that they kill corals. I read that when i googled the name.

 

[little_fish]

ive never heard of that happening, but other pest nems (aiptasia, manjo) will do that

 

[OceanCrazy]

Ty lots for the help.

Whats a good background for a reef tank?

 

[little_fish]

most people use a black or dark blue background

 

[OceanCrazy]

ok will try black

Is it true that they kill corals. I read that when i googled the name.

Maybe because they spread so fast and drown out the corals, but I'm not sure. I have them all over the place, but never concerned myself with them because I don't really have corals, except for some mushrooms on a rock (they're growing between the shrooms, too). Not sure yet if they will be harmful or not. Time will tell.

Edit:
According to wetwebmedia:

...beautiful little Corallimorpharian in the genus Pseudocorynactis. They're harmless and usually nocturnal. Not a whole lot is known about their care, but they're thought to feed on zooplankton/pods and such. For more information/photos, please Google our site, and the net, using "Pseudocorynactis'

I chose a nice purple background for the tank ( coraline algae) takes awhile to fill in but looks nice once it does...:D

 

[OceanCrazy]

How do i get that?

 

[little_fish]

Just keep good water quality, and having lighting that is more "blue" seems to encourage it to grow faster.

 

[OceanCrazy]

cause i am seeing olive colored algae growing.

 

[little_fish]

that is normal in new tanks, just keep on top of it so it doesnt grow out of control

 

[OceanCrazy]

These algae are growing really fast, just got home and 1 of the rocks is a 100% covered than when it was 20% this morning.

No fish yet, right? I forget how long your tank has been set up. How long are you leaving the lights on? If you have fish, how often are you feeding and what are you feeding? Check your nitrates.

 

[marcah]

here is a quick pic of it filling in.. as it grows it will come off further from the back glass and almost look like scalloping..

 

[OceanCrazy]

Had bad nitrates and did water changes,and its all good now.I do have fish and i feed them once a day the pellets.

ooh and lights are on at 8am and off at 7pm, is that ok?
