Very neat looking, are the hollow tubes? I can’t quite tell from the photos

 

[ISpeakForTheSeas]

Sorry

No problem- these things happen.

Waiting for a response from @ISpeakForTheSeas .

I actually don't know if I've seen something like this before, so I'm not sure what it is.

Catracchia, would you be able to get a few close up pictures of one of the larger ones from a few different angles?


A few questions to try and help figure out an ID:

-Are the tubes hollow?

-Do they move at all? If so, how? (i.e. do they move around in the tank, extend/retract, blow in the flow of the tank, expand/contract, etc.)

-Are they hard or soft?

 

[Catracchia]

no, unfortunately it's the best I can do, they look like algae because they start out green and then turn brown.
I thought about neomeris but those efflorescences and color don't convince me.
sorry for my English.

That's alright, and your English is quite good.


Interesting note on the color. I'm not familiar with an algae this offhand - the closest I can think of growth-wise are Rhipocephalus and Penicilus species, but those would be green, not brown at any stage.

I'll try to do some reading and see if I can figure something out here, but no promises.

@ISpeakForTheSeas .. I managed to pull out a tuft from inside the tank that is now invaded.
it has a calcareous consistency, it does not break but it crushes and deforms.

Now I see the resemblance with Neomeris - I'll see what I can find for you.

 

[Catracchia]

you had the same feeling as me.. surely it is from the neomeris family maybe some particular species.. I hope I can solve it without having to dismantle everything (I see it as difficult)

So, I'm feeling pretty confident it's a Halicoryne species (either Halicoryne spicata or Halicoryne wrightii), but take a look at see if you think those might be a match.

For reference (the second link shows some young/new growth nearby; they seem to start green, turn red, then develop that green and white spiky look):

species: Halicoryne spicata in Lizard Island Field Guide (Lizard Island Field Guide)

Halicoryne wrightii Finger Algae, Green Algae

Halicoryne wrightii is commonly referred to as Finger Algae, Green Algae. Difficulty in the aquarium: There are no reports available yet that this animal has already been kept in captivity successfully. Toxicity: Toxic hazard unknown.

@ISpeakForTheSeas it's really her..now I have to understand how to fight it..you were very good, thank you very much

Happy to help! You may want to see if any local fish stores or hobbyists want to take some of it from you before you get rid of all of it - I've never seen this stuff in a tank before, so it seems to be quite rare to come across, and I wouldn't be surprised if someone wanted to keep a piece or two (even if it's invasive).
