Need an ID on the blue and green stuff. It's soft like jelly and keeps the lepto from growing. It is very easy to siphon out and scrape off the glass but grows back very quickly. Any ideas on what this is and what might kill it?

 

[Redfoxtang]

This I have not seen before. Maybe some type of bacteria if it’s slimy and jelly like. Hopefully someone else has seen this before and can help you out.

It appears to have tentacles? Or almost like polyps? I've never seen that before.

 

[Mr. Crabs]

That's strange. Those things are fascinating. Try a wrasse maybe, they are good for most pests.

@Bluefishaquariums Can you try to get some better pics? Especially a pic showing those tentacles...... that’s what’s throwing me off.

Sorry. Didn’t realize I quoted the wrong person.

 

[Bluefishaquariums]

Working on getting clearer pictures. The tentacles and the blue dots are what's confusing me too

Following out of curiosity
And a bump

interesting... havent seen this. if its spreading... be weary

 

[Mr_Knightley]

It looks like a colonial tunicate potentially? The soft texture gives it away... Though it could also be either a hydroid or even a sponge?

So I was also curious what we’re looking at here too. After @Mr_Knightley suggested colonial tunicates I did some googling myself finding this...

Ascidians & Other Tunicates (Phylum Chordata: Subphylum Tunicata) of Singapore

Tunicates (phylum Chordata, subphylum Tunicata) are close relatives of the vertebrates. They possess a notochord (usually only in the larva...

Towards the bottom of this page there’s some strikingly similar examples of what might be in your tank.

Kinda cool if ya ask me

 

[Bluefishaquariums]

It is definitely the blue and green ascidians. Any idea on how to kill them without tearing the tank apart?

So I found this Article

“Ascidians struggle in captivity enough as it is; poor water quality will only push them over the cliff. Any system that houses these delicate animals should be mature and stable and have excellent water conditions.”

So if we are right about what you have than great job on having great water! But why would you want to get rid of them? Do they seem to be bothering your corals? They could be helping keeping your water quality great.

The variety in this tank grows extremely fast and inhibits the coral growth. It has overtaken a birdsnest colony.
The tunicates are probably able to survive due to the large number of well-fed fish in the system

I would try Removing them by hand and scraping them off of what ever you can.
