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

If it's in the sand and only in the sand, you can remove it by grabbing. I have had it happen that they didn't attach to anything but sand, but rarely. But if it's on the glass you will no doubt leave behind 'spores' (or whatever they are called) that will turn into several more. That's in an easy spot and is big enough to inject with straight vinegar, that's what I do. I happen to have needles from pet vaccinations....but if you don't have needles try aiptasia X or Joe's Juice. People say boiling water sprayed directly on it works too but I have not tried it.

And when your tank finishes cycling (if it isn't), just add a peppermint shrimp. He should eat them and keep your tank aiptasia free. Some people say they have had peps that wouldn't eat them, I never have. They are cheap and cool and great aiptasia eaters. There are other creatures, berghia nudibranch (you don't have enough aiptasia as they eat nothing else), Matted File Fish (they can eat coral if you plan to have coral and are not as reliable as a peppermint shrimp), Copperbanded Butterfly (not hardy and too big for your tank), and Klein's Butterfly (too big for your tank).

Your best bet is biological control for the long haul, and a peppermint shrimp is what you should try first.

Took the peppermint shrimp 2 days to find and eat it. Thanks for the help.
 
ok, this is entirely new to me in my tank, especially since i havent added anything in over 2 months(gettin ready to move and upgrading to larger system when i do). picture isnt great, from my phone and couldnt get blue out. its the red/purple sparkling gold spotted flower growing at the base on bottom right. its actually quite beautiful under the blues, when the bubbles all closed up. and its only been there a week maximum. its soft, but like a mushroom or cabbage leather. and slimes if i mess with it, but that could be the bubble being angry, though it seems to come off the thing itself. any ideas? i dont know if its a softie, or algae... and wanna prop it if i can figure out what it is. i do know it doesnt get tons of light cus the bubble is usually smothering it.

Looks like macro algae to me. Which one IDK.

*Sent from my little corner of the reef. Nano nano!*
 
whatever it is, ater moving a few rocks and giving it more light/flow, its growing. i may attempt cutting a piece and puttin it on a plug to see exactly what it turns into lol.
 
Can anyone ID these things?

theres five of them clustered together on my little piece of live rock. They dont move around, but can shrink and expand, I think depending on light. they have one opening at the free end of their bodies, and are squishy and look very fleshy, theyre kind of like the texture of a sea cucumber more so than like a sponge, if that helps.
Oh, and they also didnt respond when I molested them with a stick

They also fluoresce, which is how I first found them!

I took some great pictures with my camera, but they wouldnt upload, so here are some crappy iphone pics!

I added that line just for giggles, a job well done apparently haha

And thank you! All I could think was that they were tunicates too, they just look different than any I've seen before!
 
So I was just on liveaquaria at 3am instead of sleeping, and I found this in the divers den!
Literally looks exactly like whats on my rock, except mine are not the same color. Super cool.

Does it have a hard skeleton under it? I have something that looks very similar in my tank that I can't see the base of. I've been assuming some kind of nem but haven't found what kind yet. If you look in my album there's a shot of it in there. Mine's very very small. Been in there for 2 years at the same size.
 
Hydroid?

Hydroid?

Hi guys and gals!
Hope this is the right place to post this... I have this stalk of sponge that's on it's way out, and upon it there are these little anemone like creatures. I don't believe they are aiptasia based on everything I've seen but after searching I think they might be some sort of hydroid? Basically they are living on the dying sponge and appear to be coming out of tiny stalks. The stalks are less than a millimeter wide and maybe 3-5 mm long. They don't seem to be spreading anywhere except for on the sponge itself and well I guess I'm trying to find out if they are harmful and if I should throw them out.
