What the heck is this??!!

I have not added any live rock (just some dry marco rock), and the tank is about 13 years old. I have no idea where the live rock originally came from (we bought the house 3 1/2 years ago with the tank running).

So just wondering where this red algae came from? I have never seen it before.

Honestly speaking I've no idea although I experienced keeping quite a various types of marine plants long ago and I'm still running 2 small systems mainly for macro algae.

I've came across this algae twice and tried to keep it without success. The very 1st time was obtained from Rene/J&L long ago and that was my fault that the small frag was not properly glued to the LR and I never found it again among the forest of marine plants. The 2nd time was I didn't even have a chance to raise the small frag since the algae had turned into 80% transparent when I received because of poor shipping and cold weather.

I've encountered some of the macro algae die off and return alive after one whole year. Some unnoticeable small frags or sprouts of algae dormant for months and start growing all of a sudden. All these may be the reason why you have this algae or the new fish/coral or even a snail you newly purchased carried the spores and introduced into your system.

Well, for now it is a moot point, since my specimen is only about 1 inch across. Will see if it grows or not. And I owe ferret a frag first. I should mention though that I just saw rogair in Cgy post what looks likes the same red algae.

I should also mention that my recent phosphate spike brought out all types of algae in my tank, incl GHA, film algae, valonia and even a few of those long green weed type things. So, maybe it is all related. But my phosphates are subsiding, and I see the GHA starting to turn brown and letting go of their grip, so maybe this red algae might disappear, too.

Anyway, just another thing to keep this hobby interesting...

Don't worry for this algae seems hardy to me and I'm pretty sure that belongs to one of the slow growing species among the red macro algae.

But his is green and me likes red

I am pretty sure you won't have trouble growing it Weirdly, ornamental algae likes a bit cleaner water if I am not wrong.

I thought he had some red stuff in there, too, in one of the pics, unless that was just coralline on the rocks.
