Pix & ID: Critters that come in your rocks: the good and the bad.

Kimberly, we have probably 8 to 10 in the main tank & tons of all sizes in the fuge. They're breeding like crazy down there.

Salty, you certainly do! My condolences!
 
I am looking into getting a matted filefish...there are too many - and in too many hard to reach spots - for me to get them out manually!
 
Hope that works for you. I had an "Atlantic Green" Filefish many years ago that's now called an aiptasia filefish & many other names. I had aiptasia in my 3 & 10 gallon tanks & I was going to move it eventually into my 38, which had none, when it cleaned up the other 2. I never saw it eat any, but after 3 weeks the 3 gallon was clean. I was on the phone with a friend when a Texas thunderstorm (tornado sirens & all) came through & knocked the power out for about 5 minutes (rare in that house). There must've been a power surge & when everything came back on it was swimming upside down! It was dead the next morning. Probably just as well, they're very shy & the 10 gallon had a blue devil damsel in it that was extremely vicious to my arm & the giant hermit in with it, so it probably would have been bad in there!

White 'hair' on Live Rock?

White 'hair' on Live Rock?

This is my first 55gal. saltwater tank and I've just now started seeing this white hair-like tendrils branching off my rock.

I've had the live rock in for 10 days. When I poked at it with my net, it seemed unresponsive. All I can tell is it's stuck pretty good to the rock and it seems to be coming from little red lumps. It doesn't appear to have any sort of head or mouth like Aptasia, just those little tentacles sticking out.

Sorry for the quality but that's the best I could manage. :/

TheKman, not sure what you're asking about, can you be more specific or get a clearer/closer pic?

Mstark too far away to tell, can you move the rock closer to the glass or crop around the stuff so it's larger in the pic?
 
Ok, I tried to put it against the glass and got a picture with my phone.

It's seeming to come from those red things.

Yea it pulled off pretty easily. Some pieces were more stuck than others. I just wanted to double check what it was before I go trying to rip unknown things apart (:
 
Little tentacle...

Look in the middle of the darker area at the top.

You will see one white tentacle... It pulls back and hides when i get close to the tank...

It is about 2 inches long.

Interesting... Ohh this is from my first set of LR that I got too, not that something else could not have hitched and just moved rocks over the time.

Too far to tell, but based on what I can see & the fact it's white, I'm thinking digitate hydroid. Are you blocking the light when you get near the tank? Otherwise I haven't found them to respond to my proximity.

No the angle I came in was from a book shelf across the front, light is LED from the top. I can see it go out.. Almost like a starfish.. It moves and grasps... but it is solid white... My baby brittle ones are black and white... so it is strange.. The second I got to the tank (did not touch it) it retracted and hid... Fish swim by it and it does not hide though...

Interesting...
 
I have some white stars that are smaller than the black & white minis, but they prefer the sand & don't react when I get near the tank. If it looks just like a starfish leg it probably is, though digitate hydroids also move & grasp & stars usually stick 2 legs out.

Yeah it is only one tenticle... and does NOT look like my other brittle star legs... But the stars DO NOT pull back with I approach the tank...
