Live rock slime trails

[JetStarheart]

What are these weird slime trails leading off my liverock? Do I need to be worried?

Could be Vermatid Snails. They extend these webs as a means of acquiring food. They do look rather long for Vermatids but it's hard to judge scale.

 

[JetStarheart]

They reach the top of the tank.. Its a 75E tank

Does it start small in the beginning of the photoperiod and grow as the day goes on? Do the strings develop air bubbles?

 

[JetStarheart]

Yes there are air bubbles in the strings i never really paid attention to growth patterns.. Just really notice them at night when i am feeding

 

[Tahoe61]

It's conceivable that it could be Dinoflagellates than. I would monitor it more closely so you can get ahead of it if need be.

 

[JetStarheart]

I am missing 3 cleaner shrimp.... Could these be the culprit?

 

[Tahoe61]

Not likely. Some types of Dinoflagellates are toxic though. Not even sure of the ID yet so I would not worry yet, just keep an eye on it. If you see an increase on the amount of threads that would concern me.

I would run carbon just to be safe. Could be chemical warfare in your tank.
