#1 I just started to notice this interesting plant growing about 2 weeks ago. Any clue what it is?

#2 This has been growing on one rock 5" by 5" for the past 6 mos. It is now beginning to show up a little in other areas of the tank. every 2 mos or so It looks like it dies leaving a finger like skeleton and no green then begins to re-grow.

I've had the second one too, can't remember what its called. seems to really grow with the blue spectrum light especially if the bulbs were old. It got to be a big problem with 14k phoenix that were too old.

I just replaced my phoenix bulb. I usually change them after 6 mos but this time I waited 8 mos and now this is what I'm getting.

Any I'd would help.

62 views and not one I'd. Where are all the experts these days?

I would contact John Maloney @ Reefcleaners. I believe the first one is mermaids shot glass, not sure about the second one

Pic #2 is a member of the Genus Udotea. The finger like skeleton is the sexual reproduction stage, once that starts you are going to have a lot of Udotea. The right Sea Hare will eat it down to the rocks.

Pic #1 might be a Caulerpa. Look to see it it grows in long strands that appear to have root-like attachments to the rocks.

I'm not sure about the second one but the first one I'm almost positive is a specie of Acetabularia. If so it requires high light low water flow and is a calcerous algae so make sure there is good dissolved calcium levels in the water.
