really? 100's you say? how many adults do you have?
assasain snails dont lay many eggs thats why they are a good soloution to kill pest snails as they do breed but not at the same rate. Unless you have LOTS of adults im sceptical about the 100's myself.
they are not assasain snail eggs. i have that on my wood and i have never had my assasain in that tank!!!
100% sure.
