Assasin Snails

[Dazzlearoobob]

I recently bought 3 assasinsnails to keep my pouch snail population under control but all they ever seem to do is group together and sort of stick to one another? I'm not sure if they're actually eating the pouch snails and just grouping together to digest or whether they're unwell. Please help.

Yes its normal and you will rarely see them hunt.

Thanks Salty,
As always you've come to my rescue.lol
You're a fountain of knowledge.
What are they doing when grouped together like this?

Could be having sex or could just be a social activity, mine do it infrequently I am yet to tell the exact cause.
