 Topic: Is this Aptasia?
Posted: February 21 2007 at 2:22pm |
Ok, so I have these small things growing and spreading in my tank, I thought aptasia were much larger but I don't know. these are about 1/4 inch at the biggest and on the glass they seem to be connected. I have placed an aptasia control liquid I got for them, but it hasn't hurt them at all. they are in my gravel/sand bed, live rock, and on the glass. they don't seem to be xenia, all though they seem to spread like them on the glass. I can scrape them off the glass but within a day or two they are back. thanks in advance also any ideas on how to get rid of them, if not I will probably just take out the live rock, sand and nuke em. (I do have three pepermint shrimp in there and they haven't touched it. )

It looks like some sort of gorgonian to me.

No, it isn't aiptasia but I don't know what it is.

The first pic shows what looks like aiptasia, but you can see in the upper right area that the strands have barbs on them, kinda like green star polyps. The second pic looks really cool, but different than the first ... "Fish Net Xenia"? (j/k, totally made up name)
Aiptasia is an anemone, do those things move around at all?
Regardless, it looks cool.

Your peppermint would be hittin' those hard if they were aiptasia. That is like a peppermint shrimp Chuck a'Rama in there.
So, I'm guessing anthelia.
Edit: Anthelia would likely also be on the buffet at a peppermint shrimp Chuck a'Rama. Although there would not be a line ....

Definately not Aptasia. I say let'em stay. I have cool little things growing in my tank that I can't identify too. It's always kind of fun to look really close and see the "little" life in there.

I figured not aptaisia, but they are spreading and I don't really want them taking other corals out. they don't move around, just new ones pop up. they are not spreading real fast, I just don't want a tank full of brown stuff and nothing else. thanks for the input, I'll probably just leave them for the time being and see what happens

I totally agree it is not aptasia. Like Shane said it sure looks like Anthelia flava. Do a search and see if it matches.

My guess is not Anthelia (I don't think anthelia are a stolonifera). My quess is some type of Clavularia sp. (clove polyps).

I didn't even think of hydroid! I think you're right, especially with how quickly they are spreading.

Maybe but look at each tentacle, it has a feather like fingers. This does not look like the hydroid pictures I have been able to pull up? This leads me to a question, is the stranding behaviour what leads you to believe they are hydroids?

That picture almost certainly looks like Anthelia.

It looks similar to what I have in my tank. It has been there for over a year and hasn't seemed to bother anything, and it is so small you really have to look to see that it is there so I just don't worry about it.
Here are some pics of what I have.

I had some in a different part of the tank that look very similar to the hydroids pictured above, I was able to easily remove them. they seemed to all be connected to one stalk, however these seem to spread out horizontally, don't seem to bother anything, and they have spread from one frag "rock" to about a 11-12 diameter in a few months (nothing else seems to propigate in that tank). They are spreading up the glass alot faster though. They do tend to close up when I placed the aptasia control on them in fact I couldn't see them they would shrink or pull back so far and then the next day they would be present again. In fact it would give me false hope thinking I had eradicated them and then presto there they are. thanks for the help with the ID.

I originally thought hydroid too, however, I did not know that hydroids connect themselves to each other.
If they are spreading real fast and taking over, I would prune them back just in case they "crashed" and caused a problem (Whatever they are!)

They are not spreading real fast, its just that nothing grows(spreads, propigates) in this tank except my pom pom xenia (very slowly) so it sparked my attention when it has been spreading for the past couple of months (mind you things aren't dying either, it just always seems to be the same in there)

Clavularia or other Stolonifera all grow by stolons connecting the bases of adjacent polyps or a fiberous mat like green star polyps. The polyps are retractile.
Anthelia don't exhibit stolons, but do grow from a mat. They are part of the xenia family and have non-retractile polyps.
So, if you touch the polyps do they fully retract into a "tube" (clavularia) or do they just curl up like xenia (anthelia)?
They could also be a hydroid, but I don't know squat about them.

It sure looks like the hydroids I had in my tank. Does not hurt other corals, but spreads all over. The only way to control it is to physically pull it out. Mine has finally all disappeared, after 3 years.
