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

[GaryLCrouch]

Alright i posted a few pics below. Sorry it was with my iphone while leaving for work. I think it is a plant if anythything but really i do not know. i just saw it yesterday.

You cant see it in the pics really good but those white things are branching out from a kinda stem ( trunk ).

 

[LeslieH]

Do the branches move on their own? Expand and contract? Or just hang there?

 

[GaryLCrouch]

They look like they are just hangiing there. I will keep a closer look to make sure though.

 

[Sugar Magnolia]

Kind of looks like some dead macro algae.

i have mobs of really really long, really really skinny featherdusters with fans on them that i could only see wit a magnifying glass, but they grow in like balls of chaeto and are located in dark places like in caves or tunnels and under overhangs. been in my tank for over a year and dont seem to be a problem

Could they be Pineapple Sponges?

Does anyone know what this is?

This came off my live rock and is now hanging on the glass. Should I try and move it back to the rocks? Is it some sort of coral?

 

[cheezischrist]

no i got pineapple sponges. i just figured mine were some kind of dusters but meant to say they look almost identical to what gary has, just in largwer colonys now, to try and help him id them

It almost looks like a Kenya tree coral. You can leave it be, or use a razor blade to scrape it off the glass and then place on the rocks. Your choice.

Nudibranch-good or bad?

Nudibranch-good or bad?

Pulled this out of the tank as soon as I saw it this morning.
Should Santa put it on his naughty or nice list? :strange:
It is about a half inch long.

1. Is there any reef safe nudibranch?
2. Is it pronounced "branch" or "brank"?

 

[LeslieH]

Naughty, if you prefer soft corals to nudibranchs (pronounced brank). Genus Dermatobranchus, family Arminidae. All the members of this family whose eating habits are known seem to prefer soft corals or sea pens.

I'm guessing it's the same species as this one http://www.seaslugforum.net/find/9094 and it's undescribed.

I know a specialist who would like it (dead or alive) if you'd care to send it away.

 

[Shorty Harris]

Thanks for the info, I'll have to keep watch for more of them.
You can PM me with the details for shipping, I can try. It is relegated to a tupperware container so I can't say how long it will stay alive, I've swapped out the water a couple times today.

It doesn't need to be alive. If you have 70% (= 150 proof) or higher % alcohol on hand just throw it into some to kill it. Rubbing alcohol from the store, white rum (Baccardi 151) or a high proof vodka would be fine. that will preserve it for DNA analysis.

Put it in a small leakproof container (the smaller the better) with more alcohol. Secure the cap with waterproof tape. Put the container into a baggie or other type of sealable plastic bag. Now it's ready to be shipped. I'll send you my address in a PM.

Many thanks --

 

[LeslieH]

Double post, sorry....

 

[Shorty Harris]

Okay, it's in a small vial of of alcohol. Got your address, will send it on Tuesday if my jury duty is cancelled that day, otherwise it will go out on Wednesday.

Super! Angel - the co-author of nudi books for the Caribbean & Indo-Pacific - will put it to good use. Thanks!

Are your rocks & critters most Indo-Pacific?

 

[Tristen]

No idea where this guy came from... It's like a muscle but only half of one... Or a snail but only kinda ...

 

[nanoreef heaven]

Stomatella snail

*Sent from my little corner of the reef. Nano nano!*

 

[Shorty Harris]

I have just your typical beginner polyps, and a few LPS and SPS. I'm guessing its Pacific. Not sure about where the CUC stuff come from.

BTW, watch your mailbox, shipped it from the post office today.
