pyramid snails after one year clamless

[jpmunoz]

I had pyramid snails that did my clam in over a year ago. They were the type that also attached to snails, so my larger snails also perished. I recently added some large turbos and other snails. They all got covered in pyramid snails after about two months. Other than ditching the whole setup is there a way to bring clams back to my reef? Do they ever die out?

I'd add a Yellow Coris Wrasse, they gobble them up.

Maybe they came in on the newly added snails?
