Pix & ID: Critters that come in your rocks: the good and the bad. - Page 62

A while back I had posted about some decorator crabs that came into my tank as hitchhikers... and how they were taking zoa polyps and xenia's and decorating themselves and how I thought it was cool. One crab even cut a chunk of my leather coral and put it on his back. Well the novelty has worn off... after pushing them away from my Kenya tree for a couple days they were relocated to the refugium, where they promptly began to eat the caulerpa(can't grow chaeto to save my life) so they are have no been relocated to the overflow box(part that sits on the outside). There's a sponge that I keep on the tube in there to catch particles so I guess they can eat what goes in there... and if I really want to see them I can look at the back of the tank... there's only one more place they can go if that doesn't work out!

Killgore · 11/25/2012, 11:39 AM

At least now I can finally get some zoa's again

SushiGirl · 11/25/2012, 12:15 PM

Why not see if someone else wants them?

Killgore · 11/25/2012, 07:46 PM

But I like them too much! I still think they are cool! I checked on them earlier and they were busy eating things off the sponge... I don't think they care where they are. I'm debating now if I want to set up a smaller separate tank for them and some other crabs. I'm thinking I can put them back in the refugium when it gets over grown, but I'm concerned that if they eat the plants that have locked up the phosphates and nitrates that they will excrete it back as waste which would be counter productive.

So I am new to the hobby and I have had my tank up for a few months now and am combating aiptasia so I moved my rock around and tonight was looking for aiptasia to x tonight and saw this.

Any help would be great. Also notice its got a pod and I assume its going to eat it.

Have had my 37 gallon reef going about 2 months and starting to notice all kind of weird stuff on the rocks. Anyone know what this is? Looks like some sort of small yellow plant. Is it bad?

It looks like Halimeda Macroalgae to me. If it's hard, then it probably is. Halimeda is a good guy some people pay for, but it can "go sexual" and mess with water parameters.

Cabe · 11/29/2012, 10:22 AM

Thanks George! I think that's it!

Here is another thing that came out of the rocks and is now hanging on the side glass of the tank. Seems to be doing ok, but looks a little strange not attached to the rocks.any idea what it is? Will it make it or should I try and relocate it?

Halimeda can go sexual, are you sure? It doesn't say anything like that on liveaquaria that you linked. I've only heard that it was a cualerpa that was a risk of going sexual.

Yes, mine did.

Halimeda: The Cactus Algae

Quote:

Caulerpa fanciers are usually familiar with those algae's method of sexual reproduction. A colony will expel its gametes along with all of its cytoplasm, leaving a snow white or transparent (and very dead) clump of algae and a pea soup green aquarium in its wake. Halimeda's sexual reproduction is similar, but with the added benefit of a known warning indicator. Hours before releasing gametes, the algae will turn pale white with dots of very dark green or almost black along the edges of the thalli.

Well you learn something in this hobby everyday!

ArrowCrab · 11/29/2012, 08:26 PM

This has been on my LR since I got the piece; pretty sure it's been dead the whole time but I'm still interested in finding out what it was.

Those are the empty shells of a bivalve that glued itself to the rock & later died.

Bukwha · 12/01/2012, 09:50 AM

SushiGirl · 12/01/2012, 11:28 AM

Last pic is aiptasia, you'll want to get rid of those.
Can't tell what the first pic is.

jerkyjunky · 12/02/2012, 01:37 PM

It is soft, and sways in the current. Also is very fuzzy looking like cotton.

aquanooby · 12/02/2012, 08:15 PM

curious what these couple things might be...

and

these little green deals they are tiny so I am sorry for the blur
and this thing in the upper center in the hole

aquanooby · 12/02/2012, 08:17 PM

I also think I have a feather duster but its smallin strong current

SushiGirl · 12/02/2012, 08:37 PM

2nd pic are featherdusters.
3rd is halimeda algae & some other algae thing I think, I've had them in my tanks & never seen them grow.
No idea on the first pic, not sure where the 2nd item you're wanting identified even is.
