What is that glowing?

reefan2015 · 05/06/2015, 02:05 PM

so last night when I went and looked at tank there was a pink glowing section on some recently (2 weeks ago) installed dead rock. I have LED lighting and it was under the black light setting. So I turned on the full spectrum light to see what it was and it looked clear... almost like little tiny nodes. There is no hair for tentacles coming from it at all. It is important to note that I do have live rocks and sand in the tank as well. It has been up and running now for about 7 weeks. I recently went through an ammonia spike but it appears that I now have cycled completely.

72 gallon
two clown fish
two cleaner shrimp
1 B cardinal fish (second died during spike RIP)
2 turbo snails
1 feather duster
1 blue legged hermit crab
mushrooms
green zoanthids

everything seems very happy, eating well and growing. all are babies

can not see it with a camera so a pic right now is not available.

Foraminiferans perhaps? These can appear as small pink nodules sometimes.

Usually bleaching coralline give a slight pink fluorescence under blue led

These glow with the lights off though

There was no coralline algae on it prior. It was bare rock... It looks pink under blue led and looks like Quartz with full spectrum lights on

Would there needed to be coralline there first?
