Are you intending on hatching the clutch? I have snails too... I hatched one very small clutch and got 100 odd more. I'm not hatching any more clutches until most of mine die of naturally as even though I have 6 tanks running I don't have room for 100s more!
We have 3 tanks and yup there are snails in all of them...lots of snails in the one tank I have mystery snails and a couple nerite racer snails too
When I first started with one tank the first clutch hatched and there were a lot but the last few recent ones didn't have any snails tho
More than 10 years
I have snails in all 6 of mine... I've given a lot away too lol in the meantime I've just raised my water levels to prevent it from happening! Here's one of mine!
