What is this red stuff?!

its been growing like crazy and makes my poor colt coral look sad and small lol. ive tried looking it up with no luck, anyone have an idea?

 

I'm interested to see responses on this. It's really pretty! I've not seen it before.

 

i was thinking the same thing! wow this stuff is a nice touch to the tank! this is my biggest piece i have about 2 to 3 inches and then i have a couple other quarter sized pieces starting to grow also elsewhere in the tank that are darker in color

 

Look here, I can not tell for sure need a better image of the structure.

thats the best photo i can get since it sits at a strange angle and it hangs over the structure itself.. it reminds me of the colt coral under the fan like leaves.. it almost has small branches

 

I used to have algae like that, it preferred higher salinity IMO. Never got an accurate ID however. If it were me I'd take it over colt coral any day.

Following along for an accurate ID.

 

I found out what it was from a local shop and it's a form of Macro Algea!

 

Nemastoma vs Dragons breath/Halymenia. It's in the link I gave you above.
