Blob with tenticles

[BlurCaze]

Hi all,

Discovered this in the sump today, it's somewhat aiptasia looking but being that the sump has no light, it wouldn't be an ideal spot for aiptasia?

Any idea what it could be?
Thanks

I say aiptasia. They can deal with very very low light insanely well. I've had them in my sump as well and they even survived in the skimmer.

If humanity nukes earth to dust and ashes roaches and aiptasia are the only things that will survive. I'm not entirely sure about roaches though.

Treating it at this spot might be a bit difficult. If you can lower the water level kalkpaste might work there. You need to get rid of the whole foot or it will regrow even from the tiniest residues.
