Ouch - an unknown stinger!

mandtj · Apr 20, 2021

This has appeared, growing slowly over the last few months. Initially it was quite interesting, especially the way it reacted when disturbed - see the video clip

Then I was fiddling in the tank 3 or 4 days ago and the back of my hand brushed against it - it ended up very sore and left a scratchy pimply rash which is very slowly fading.
I'm going to get rid of it but before I do I'd really like to know what it is...I've tried all the permutations I can think of in google searches and not got very close...cheers!

Does this help @vetteguy53081, @Eagle_Steve?? This is after OP poked it. It reacted almost like a blooming flower.

May be sympodium and would likely cause reaction so does alveopora and certain zoa and even goniopora

For the future, consider Aqua gloves at only $20

Is agree it may be one of the 3 mentioned. (Not zoa lol). It could also be tubilora (pipe organ)

one way to tell,

sympodium has 8 tentacles and encrusts.

alevopora has 12 fat looking ones and forms either a branching or connected skeleton

goniopora has 24 thin ones and forms either a branching or connected skeleton.

tubipora has 8 tentacles, but each one has its own “pipe” to retract back into. (Edit: corrected fat finger spelling lol)

@mandtj Best bet is to google each one and compare the images that come up to what you have in your tank.

@mandtj ,soft or hard body??

mandtj · Apr 20, 2021

Thanks for all the interest guys!

@fishguy242

Its neither hard or soft really...more like some of the tougher tufty seaweeds you might find...originally that's what I thought it might have been when it first appeared - then I started noticing the reaction when disturbed. Grabbed another pic - easier to see into the structure of it.

And my hand lol

Just managed a closeup of some of the tiny heads open. They don't retract, just close over and go white when disturbed

Looks like I might have found it!

The Iramo: a highly dangerous aquarium coral

Given how many dangerous creatures are readily available in the aquarium industry, it’s easy to think that aquarists might have a tendency towards masochism.

You know those tiny jellyfish that show up in the beginning on people's glass but that never survive?

This is them surviving

Nausithoe racemosa

And they are beautiful

Edit: looks like someone was faster

If that is what is, I haven’t seen them in almost 20 years. But looking back at the structure of your last post, it does look just like some what came in on some stuff my dad got from Guam years ago. He kept it in his tank until his copperband decided to eat it all lol. Then a torch got a hold of the other small colony one night and melted it.

If it was me, I would keep, but not touch lol. Also, I feel your pain. Got thrown into a fire coral a few years ago by a rouge current and talk about pain. It sucked.
