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

[nanoreef heaven]

I'd like to know what those little star things are also. About a month about I had about 6 in one of my tanks but haven't seen them lately.

TheKman, looks like a hydroid jellyfish. Common in new tanks, the population willl boom then die out.

Dustin, you are correct on the ID. It's fine. Great pic, by the way.

Thanks SushiGirl. I think most likely they came in some chaeto I recently added to the sump. If I had to make my tank fallow it was time to do so as I don't have the big tank tied into my system yet.

Great thread as there are not that many sources out there with a lot of the pests/critters outlined....

So heres a new guy that just recently showed up.. he's less than 1/2 inch right now.. no clue where he came from and this is the best shot I can get..



Hope he isn't too bad.. i like him! which means.. he's probably really bad... =(

Ball anemone. Most people say they aren't as bad as aiptasia & don't spread as fast, but I'm having a huge battle in my tank that I seem to be losing, from one a year ago to at least over 30 (that I can see to count & who knows what's in the caves & the back) now in my 55. Opinions may vary, but I say kill it with fire now.

Of course.. i liked it too... which instantly told me it was bad for me.. =D thanks for the ID!

[SushiGirl]

If it helps any, yours looks prettier than mine LOL. They aren't truly anemones, but psuedocorynactis, which puts them closer to mushrooms. Still invasive, IME. At least mine have been, anyway. I've now tried 4 things to kill them in the tank & I've only succeeded in killing one for sure. The rest came back either immediately or within a day.

[Lyvric]

It's a dully grey with black 'veins'. It's not moving anywhere, anyone know what it is?

[SushiGirl]

Seems like liver sponge.

Try looking up scypha sponges, spirorbid worms and asterina stars. The first two are harmless, but the asterina stars have been reported to eat certain corals, so you might want to think about removing those. HTH.

[SushiGirl]

Spirals are spirorbid worms (featherdusters).
Thanks, cloak, was on my phone & couldn't see pics well enough to answer.

[greenvillecoins]

thanks so much

Are these Aptasias? I bought some Aptasia-X and got rid of all of the other Aptasias on this rock. These are on I think old coral attached to the live clam that came on my LR I got when I first established my tank.

[nanoreef heaven]

Those look like ball tip anemones. Some consider them a pest some don't.

[nanoreef heaven]

Then again are they coming out of stalks?

Sent from my Nexus 7 using Xparent Pink Tapatalk 2

[Cymonous]

Yes, they do appear to be coming out of the stalks

[nanoreef heaven]

I'm not sure if they have a stalk or if the just are growing out of that old coral. But I have an orange ball anemone that looks similar minus the stalks. Try looking them up. I attached a pic mine close to the clam on a rock. Sorry bad quality I just was on tablet and used my tablet to take pic. uploadfromtaptalk1344289989665.jpg

Found this snail hangin out in my Zoas. Doesnt seem to be doing anything. Pyramid snail?

[SushiGirl]

Cymonous, looks like hidden cup coral.

Steve718, could be, though it's awfully curvy. Might be better off starting a thread in "Other Inverts" asking for a snail ID. There are a couple of experts out there that should be able to help.

[Itsathermal]

Hello, i am new to posting in the forum so i hope this is acceptable and in the right place.

I found these cruising around the base of the flesh on my hammer coral. Also found little clutches of eggs there. The big one is 2.5-3 in long and they are mostly flat. They respond and move quickly when i touched them with the tip of a pen. Any idea what they could be?

[Dustin1300]

Looks like some sort of flatworm, possibly a planarian but cannot confirm with the picture.

[nanoreef heaven]

Nasty flatworm of some sort. Agreed.

I was leaning towards a flatworm as well but thought with their size that they might be something else. Thank you everyone for your help.
