Need a bunch of ID's.

[CoreyK]

Would appreciate any input/ID's on these hithikers I've found.

Tank is an 8g BC with ~ 12lbs of LR. Just finished cycling.

Just want to know if any of these are bad/reason for concern.

 

1: Snail

 

2: Some sort of coral that's been bleached?

It was all green several weeks ago, and now is almost totally white.

If it's alive, is it saveable?

The little bumps extend when the light is on. (Sorry, am a complete coral newb).

 

3: There's also some little critters who call it home.

There's 3 or 4 sets of little wavy arms that pop in and out, I'm assuming filter feeding.

Here's one, in and out:

 

 

4: I have a few little mini colonies of these guys.

Good or bad? My hermit seems to have eaten the tufts off of the other little colony.

 

 

The next two are difficult to get pictures of and to describe.

 

5: The first is an opaque little anemone looking guy with yellowish balls on the end of the stalks.

The stalks meet in the middle and wave around slowly from time to time.

It is on the right side of the rock, middle of the picture.

 

6: This next one has me clueless.

They're like two tiny skinny arms that seem to come up from the rock and feel around.

They can extend and distend from the rock.

This morning, when I turned the lights on, I *swear* I saw them holding a little larvae type thing, coming out of the rock, and releasing it.

Any ideas?

 

(It's difficult to see; both arms are visible in this picture, laying down flat against the rock)

 

(and one arm is visible here, reaching vertically)

 

Any help on the ID's would be awesome!

Thanks.

Picture 2 looks like some kind of sps. My guess would be montiporia digitata. Chances are it won't survive in a new tank. SPS need an established tank with good light. 3 are serpulid worms kinda like feather dusters, harmless. 4 looks like common brown polyps (palythoa)or some sort of hydroid. 5 looks like psuedocornyactus anemone (orange ball anemone). 6 looks like a spionid worm. They are harmless but may irritate some corals with their tentacles. If I may ask where did you get live rock with such good hitchhikers.

1. harmless algae grazer.

2.see above

3.barnical (thats a tough one, i'll give ya that.)

4. hydroid

5.fish eater

6.harmless (worm)

 

so i've given you a few clues, all are very common, and all can be found in this forum (last couple of pages. if ya get stuck, or need another clue, just ask.

 

 

just kidding

(2,5 and 6 where already given to you)

[willyboy]

but if 5 gets big enough it can eat fish. I've never seen one big enough to do that on N-R.

 

Number one is a collonista snail. They reproduce well, and are good algae grazers (already mentioned).

 

In pic three (a & I agree that that is a barnacle in the middle. You can see a small fan worm/feather duster. Looking back at number 2 you can see where the barnacle is and the fan worm/feather duster at the bottom.

Nice pics! You have some very nice hitch hikers.

 

Here is some more info on some of your creatures:

 

Collonista:

 

"Collonista are "mini-Turbo snails." They are seldom purchased by hobbyists, but are relatively common in reef tanks anyway, because they appear to hitchhike in on live rock or in some live sand. When hobbyists first see them, they presume them to be "baby" grazers of some sort. Instead, they have some of these animals. They reach a maximum adult size of about 1/4th inch (6 mm) in height and diameter. They are often tan to white and have mottled brown color patterns on the shell. They can be distinguished from all other Trochoideans by their small size and the presence of a small pit or hole in the center of the calcareous operculum that plugs the aperture. They reproduce well in aquaria, and are quite good grazers. If present in large numbers, they may effectively replace all other grazers in our systems."(From http://www.reefkeeping.com/issues/2004-05/rs/index.php

The 2-tentacled worm may be a member of the Spionidae or Chaetopteridae families. Scroll down to that section of this article:

I'll bet the "larva" you saw was a fecal/waste packet...I've seen many worms pass these out of their tubes or their holes in the rock.

Holy crap! Thanks Diane! That's the most informative/helpful post I ever could have asked for! I really appreciate all the time and effort you put into that. Well done.

And thanks very much to everyone else as well!

 

This is my first reef tank, and I'm absolutely amazed at all the life that is budding in my tank. It's quite amazing.

I got the LR at my LFS (Preuss Pets in Lansing, MI), who I would confidently claim is the best LFS in Michigan.

There's a ton of life on the rocks other that what's in this thread, I just didn't need ID's on them

 

So it sounds like nothing's harmful in the tank except for the fish eater.

Any suggestions on getting rid of it?

Is it possible to remove without killing it?

[formerly icyuodd/icyoud2]

dont get rid of it. they have to be much much bigger to eat fish.

i have a few in my system (going on 3 years) and there still no bigger than a quarter (keep splitting)

 

very cool little critters.

1 Yup.

2 Nope....Porites.

3 Could be a boring worm or a barnical?

4 Hard Tube variety that spread like wild fire and bore into the rock. Your seeing about half of the actualy size.

Pop them off the rock asap or they will spread.

5 Ball anemone (takes a LONG time to become large enough to eat a fish larger than clown goby)

6 Yup
