Why do my conchs keep piling sand in tank

[milomlo]

Doing this? it isn't just sand. They did it in the back and today when I did a water change I was going to spread it out. But it is like gel or something. Are they mating or something??

Those kinda look like cone snails, not conchs

And cone snails are deadly venomous

Google cone snails and conchs

No. They're conches.

 

[milomlo]

Anyone know why they do this to the sand sometimes?

 

[Grizz]

I think there breeding mine are doing the same thing Started a few days ago

 

[uh.oh...]

I knew a guy at a lfs (employee) who called them con "ches" with a "ch" sound. As in Charles. I never could really take him that seriously
