Popped up the other day...coral?

[Soylent Wrasse]

So I've had this rock in my systems for about three months now. Under the actinic light I noticed these little orange/red glowing cluster, and took some pics.

Tiny, glow in the dark under the actinics (and it isn't even a kinda, they are lava orange under the blue lights). Rock came from the Atlantic, and they are tiny, roughly pinhead sized little circles. I don't have any zoa's in the tank, so there isn't contamination from anywhere else. I don't think it's algae, as I've had some algae that glowed, but not anywhere near the bright lava orange they do under the actinics.

Any good online florida coral ID guides?

Thanks

Let them grow, all life matters. Sorry, they look nice but I can't help you.

Red grape algae.

I like red grape algae. Some sponges come that color but usually not smooth like that.

I like your screen name too

It's not growing anywhere near quickly like algae does. I'll just have to wait in and see I suppose

Your pic isn’t clear so based on your description I’d say it may be red bubble algae.

So glad to happen on this as I have the exact same thing in a few spots. Definitely not bubble algae, it has a different feel to the touch. Also they are very flat. Like snail eggs, but orange. I was guessing sponge when i first saw it, but months now no growth.

Did yours stay the same size roughly? @Anihiel1

I noticed them maybe a month or so ago? Have not changed one iota. Also in a cluster of three like yours.

Maybe a bad pic then. These look red and round, like bubble algae. Sim to attached.

The attached photo looks like a type of red bubble algae. There are a few different varieties, and they aren't necessarily spherical like green bubble algae. They often have 'stems', and there are even branching varieties that are good for aquaria due to being easy to prune.
