Trochus snail spawning

[stuiees]

Noticed all 4 of my trochus snails climbed to the top of the rocks and started to stand up. Pulled out my phone and was able to catch them all spawning at the same time. This went on for about 10 min

They usually do this in response to a parameter shift, increase / decrease of alkalinity, water change, sudden temp shift etc…

I did do my weekly water change yesterday. I will check my parameters now to make sure nothing is out of whack. Thanks for the heads up
