That might be a sponge, kinda blurry.

Alright thanks!

Bad guy..... Only around 3 to 4 feet long, wiped out almost all of my turbo snail population and we are talking about over 200 to 300.

I let the SushiGirl name the bad boy

Tahir

Can't see it's head. If it killed a bunch of stuff, I'd guess either eunicid or oenone fuldiga, but I don't know if the latter come in black or not.

Need confirmation on these: Asterina Star and bristleworm? The suspected bristleworm seemed to have a dark bluish middle third if that means anything.

Yep, you got it.

 

[SushiGirl]

Confirmed.

I've seen many of these little guys zooming around on our rocks. Most of them are around a 1/16" long.

Sorry for the lack of detail in the picture but it's as good as I could get. I couldn't tell if they have eyes or not. Possible to ID?

Thanks for all the help!

That's a munnid isopod. Harmless detrivore. :thumbsup:

We have thousands of little white spots popping up all over our live rocks.

Ah, I can see the little spirals now. Spirorbid (featherduster) worms.

Just discovered this today in my 3 month old nano, kinda looks like aiptasia but when i battled it in my other tank they were all clear or a brown tint this is purple and not clear.
Sorry for the poor quality pic but not much room between the tank and wall had to stick my phone in and take pics blindly.

 

[SushiGirl]

Lots of different types & colors of aiptasia. Looks like one to me.
