If it helps any, this is what it looks like under a normal flashlight (tank lights just turned off)

I presume these are small mojano?

[AlSimmons]

Protopalythoas I believe.

well that would be nicer. I have a few other zoa in the tank, but nothing with this coloration. maybe it hitched on the original rock work. The colors made me worry it was a bad one though.

Hi Guys,

i have those guys in my sand, this was recorded with a 500x microscope looking at my sand bed around 1/2" below the sand line. I did some research but didn't see/find anything.



and picture



Thanks

[PeterBel]

A better picture of it!

I picked up this 29 biocube tank second had and was watching closely to see some of the lesser seen residents during feeding and would like some help with id's.





Best shot I could get will post a couple more of these but not much better the crawled in and out of the rock during feeding time.


I am assuming this is a bristle worm can you please confirm if it good or not.




Lastly this is a shot of the back wall, what are these hard white dots and what are these hard white tubes, some type of worm I assume because during feeding a few will put out "feather dusters" The white dots are inside the filter area as well.




Thanks for the help

[PeterBel]

First 2 are Amphipods, i do believe also the 3rd picture is a Bristle Worm.

[worm5406]

I agree. ALL are good. Bristles clean out the cracks in the rock.

[gough25]

Any idea about the back wall?

[worm5406]

All I see on the backwall is Feather dusters.

Even the hard white dots are feather dusters? Just asking because they are even in the filtration area.

Hi all just wondering if anyone could give me a hand on the I'D of two unusual things. Atlist for me lol



The first one is this filter feeder that is reproducing quite fast in my aquarium I really like them but I have a few on some zoas so would like to know your opinion on this. Are they something that is bad for my tank?




This second one could be confused whith an aiptasia but it looks like a feather duster worm whith out the tube, wend I touch it it retract as a aiptasia but it is very bright in colour as aips are just pale in colour I'd say.

Thanks in advance

Those hard white dots are Spirorbid worms, a type of feather duster. The link below might help.

Do not touch the bristle worms. They will sting.my fingers swelled up like hot dogs for weeks. I use tweezers or hemostats to remove the big ones.

Leave the Bristle Worms alone. They clean crevasas and eat all sorts of things.

I moved some rocks and found this



It's covered in a gooey sponge like webbing and looks to have an entrance hole. What kind of critter would make this/live in it?

[alcimedes]

Sure it's not some kind of sponge, and something just lives in that hole which is keeping it clean as it goes in and out each night?

It def looks and feel like sponge. I'm wondering what kind of critter would live in the hole. I'll keep an eye on it and see if I can spot the inhabitants 😀

Hi, I was wondering if someone could help me ID this critter on one of my rocks. Its usually hiding during the day, but I was able to snap a picture early this morning. Thanks for the help.

I finally found what it is, for people that might be interested to know, those are "Seed Shrimp" or Ostracod. Apparently, there is around 70 000 variety of it in Salt and fresh water. Most of them of reef safe being filter or detritus feeder.

Can someone please tell me what this is. Found it on the glass today with naked eye. This is 40 times magnified. Also, hahaha can someone tell me how to put a picture up in this post from an iPhone. Keeps asking for url can't really do that from my photo album. Got to be an easy way I'm sure.

Upload the photo to a site like imgur.com then you'll get a URL to use to post here.
