sea hare vs pyramidellid

[Myriam]

Hi,
I had some pyramidellids snails that killed most of my astrae and turbo snails. Then I brushed the remaining 3 turbo twice a week to remove the pyrams during several months.
I thought I didn't have pyrams anymore so I bought other snails and a sea hare (dolabella) to control the algea which are coming bigger and bigger.
I found that I still have some pyrams in my tank.
Question: are the pyramidellids snails can kill my lovely sea hare?
Note also, the pyrams don't seems to attack my maxima clam. I never see any on it or under it.
Thank you!

pyrams are usually species specific, meaning they eat only one thing and everything else should be fine. i have never heard of any that go after sea hares, so i think you should be fine just watch out for the power heads.

OK, thank you very much! This explain why my clam doesn't get attack
My powerheads are stream tunze and apparently they are safer than seio for exemple, but I always check just in case.
