Fine White Particle Shooting Out From Rock

[boxfish]

Was looking at my tank just now and saw a wonderful scene...

white egg-like particle "shooting" out from behind a piece of rock continuously for minutes....filling the whole tank entirely...baby fire goby seems to be eating it...

unfortunately angle too acute can't see whta's shooting out those particle.

definitely not dust stir up by fish...

hmm.... wonder what's that...saw this in coral documentary when coral spawn..

hopefully is not hairy crab

i saw my LR do that once...spawning?????...LR????

Looks like someone is fooling ard inside the LR...

[boxfish]

does not look like something fooling around... because the size of those particles that were shoot out is quite about the same...

hmmmm

Some burrowing organisms in your live rock squirting debri out of their homes.

cud be probably sml mantis shrimp inside yr live rocks doing house cleaning. Do u hv an urchin? cos urchins do that as well. Gives off cloudy eggs once in a while .

I do have this problem 2 ! But seems more like fine debris instead of "eggs". Luckily it is only 1 LR doing it .

Another possibility= sea squirt
