Amphipods, copopods, isopods

Those white things, look up spirobidae worms and see if thats it.

Doesn't look like it. The lights are about to come on so I may be able to get a better pic. Here's one but not sure you can get anything from it.

Do they looke like these?

Ok the lights are on and I am really looking hard to see what they may be.
The overflow box looks like the top pic from this thread:

The ones on the rocks look like Serpulid polychaete from Reefnuts pic about a 1/4 way down:

The white dots aren't as noticeably curled like what you show Thomas. They are more like donuts with a lot of areas showing white strinfs like Reefnuts pic. The bugs that are moving around are brownish and tiny. I think I can see antennas and several legs. They are very quick. The white dots are spreading like crazy!!

Let me also say that I tried to scrpae a few off so I could take a better look and they are very hard.

Bump for identification help.

Hi I was just wondering, are those little tiny pinkish dots that crawl on the glass of the tank beneficial or harmful, also I have little tiny white dots with little thin legs on the glass of my tank are those are harmful, I just got coral and I think that is where they came from and I do have fish that eat them, my tang is always picking at the glass.
So my question is are these little guys harmfull that I just described?

Sounds like isopods or copepods, I have them crawling all over my refugium, They are very benifical, free food for fish, and an important part of any infauna (that is in the sand bed).

Thanks Thomas. They are even on the snail shells but never on the fish. Maybe when I see th efish picking at the rocks, they could not only be eating algae but maybe the little bugs too.

OK, so I got so new Lr yesterday at my LFS and I have found some of these little critters in my tank. Should I be looking for the bad ones? I also found pinhead sized bright pink snails, are they bad? Also a tube like thing that streches out about 1 inch or so. It looks like a co

eb. Any ideas?

 

[nancysalt]

oops I meant to sat cob web like.

We just set up our sump refugium and got some live rock rubble from the LFS havent seen any live copepods but have notice some copepod molts in the filter transparent so hopefully the rubble has some in it but probably going to order some anyways

Is there any way to "jump start" the population in my new tank? I have 60lbs of LR and another 40 curing. I would like to be able to keep a mandarin in a year.
Thanks

Clown52, I think your population will do fine naturally, however you could take a 1 square inch of filter floss, lace it with phyto or microvert liquid food and wedge it between two rocks in a low flow area, they love that stuff. The larger amphipods prefer fish detritus.

 

[reefdweler]

What are those? I have tons of them in my sump and overflow.

Those were photo's of Pinapple sponges, harmless filter feeders often gathring in low light areas like overflows, sumps, skimmers and wet/dry's.
