What the heck is this??!!

[Reef Pilot]

It is bright red (quite pretty actually), and about an inch across. Never noticed it until a couple days ago, as it is partially hidden behind a rock in the back of my tank. I thought maybe a sponge, but it moves a bit with the water currents unlike some other sponges (not red) that I do have. Or some kind of macro algae?

I am guessing it is Peyssonnelia squamaria. Some type Chloroplast, so yes some algea. Its pretty cool looking, I remembers seeing the same thing at Wais.

Yeah, I guess that is possible. Doesn't quite match the shape and colour, but I haven't found any closer resemblance.

Its colourful though
I guess the tang doesn't eat it

No,... not yet. Yeah, it is really bright red. If it was a coral, would probably be worth a fortune...LOL.

Will see how it grows. Like I said, first saw it only a couple days ago. Hope it is not some bad pest, though, that will overrun my tank.

That's a red macro algae known as Predaea with gelatinous thalli . I should have a frag last year send to me from a guy at Edmonton but the plant didn't survive due to cold weather & poor packing. If you don't want it, I'll love to purchase or trade from you.

I googled that, and yes, that could be it. Except mine is much brighter red than the internet pics I saw.

So, are you telling me this is worth something?...LOL

I am going to let it grow out a bit, and see what it looks like. Keep in touch.

I look forward to that so that I can have a frag from you.

Yeah, weird to say, but it is probably the purdiest live thing in my tank right now. Any red algae that I have ever seen is a dull orange/red. But this one is a deep bright red.

Maybe I could give it a designer algae name... LOL.
