What is this mushroom?

[Jef Challe]

Split/forked tentacles, blue and green. Body looks like full of flowing glowstick radioactive ooze. Any thoughts eould be appreciated.

It's a Rhodactis sp. Probably rhodactis rhodostoma. The amount of green, purple and brown can vary significantly depending on light. From what I've seen at least some species/genotypes can continue to grow as they age and can get quite huge. I've got some in my tanks that are plate size.

WOW! How long did they take to get that size? Do you have any photos?

About 6-7 years. It was just rehomed, here's pics of it with some daughters from the 90 (left side) it was in and the 220 it's in now.

Thank you. Very nice tank. Congratulations.

Thanks. Looks very similar, with the extension being different maybe. Mine is literally dinner plate size if Out of direct flow, rarely if ever splitting without some prompting. Appreciate the help.
