help idenitify

Hello fellowes,

I went on vacation, and when I come back something grew in my tank becasue before I didn't notice it. I saw it make little sand heaps at the bottom. I couldn't resist the tentation and took a big spoon and scooped the sand up to check what was in the sand. Take a look at the pictures in attach. What is it?

Greetings,

GM

 

welcome to 3reef! I'd take it out and place it in a bowl, and then destroy its home to get a good look at it.

 

I pity the animals in your tank, the moment that you don't know them, you crush them? Good going for keeping up the good work and protecting the nature!!!!!!

 

I said crush its home, not the worm or whatever. the home/burrow is made up of mucus and sand. Im sure it can remake it with no problems since it obviuosly made it recently.

Furthermore, you need to know a little bit about the person before you go making acquisitions.

 

So if you see a poisonous spider in your house next to your child, you leave it be? Cause if you crushed it, you wouldn't be protecting "nature". I dont know about you, but I'd crush the heck out of it.

 

I got this answer on an e-mail I sent to the university from Giacomo Bernardi:

"What you have here is a polychaete worm by the name of Pectinaria (I am
not sure of the species exactly but it is probably gouldii). It is
commonly known as the ice cream cone worm and it constructs a conical tube
made of a single layer of sand grains. It burrows in sand and uses the
stout chaetae just underneath its operculum to pull itself through the
sand."

 

Did they say if it's beneficial/dangerous? Reef safe? What it eats? That's wild! I've never seen anything like it!

 

Geekdiesel!! It depended on how bad my kids were pissing me off that day if I would crush the spider or not!!!!!! lmao NATURE WRECKER!!!!!!!

 

LMAO

 

man, you got a pectinarid in your tank?! so cool, Ive only ever seen these in the wild and never as a hitcher in a tank. i dearly hope you dont kill it for two reasons:
a) it's just plain cool and as far as i know unheard of in home aquaria
and b) beneficial. it sifts through the sand and eats detritus.
