weird asteria snail behaviour

[mikenfairfield]

I'vd got a weird thing that started this afternoon in my 120g tank. Almost all of my astrea snail are grouped in the top back of the aquarium around the overflows. In some cases their climbing on top of each other .

The're all squirting into the water what appears to be super small clumps of air bubbles or even sometimes looks like puffs of smoke.

This is either some weird type mating ritual or I have something seriously going on.

All tank conditions are perfect that I can measure (pH 8.3, salinity 1.024, nitrate 0, nitrite 0, phophate 0, calcium 480, temp-7.

Any ideas on what's going on?

temp seems a little cool...7* burrrr.....

just kidding...

sounds like they may be spawning...not sure though...the group thing is a little crazy...mind you i dont even know how snails spawn...but from what i have seen from clams and bristle worms...i am sure snails would be the same..

they are spawning.. pretty common.. your coral may enjoy the snail egg/sperm meal..
