Assassin Snail Question

Basic question, do Assassin snails need a partner to reproduce or can they create babies all on their own?

Also, when they do start procreating how many can they have at a time?

They need a M/F pair, with no real way of sexing them. Not sure on number babies. I started with about 4 or 5 and ended up with 40 or so total, but I'm not sure if it was 1M/4F, 4M/1F but a few of those tanks are low low pH tanks for crystal shrimp, so their rates may be a lot lower as snails usually like a higher pH tank, higher gH (calcium) tank.

20g platy, , 2 x 10g shrimp, 3 x 20g shrimp, 7.5g shrimp and 1 great dane/mastiff puppy.

Yes the do need a partner, the better they are feed (snails/food) more often they produce. They lay one single egg at a time, it's hard to say how many the can they lay, but it is only one at time.. They look like diamonds covered with a gel layer.. I have breed them for 3 years now and still not able to figure out the sex of them...

Temps that I have been able to breed them in is a wide range from 70-90, ph I don't think bother them.. They will lay the eggs any where in the tank, if you have a sponge filter that is the number one spot.

so I know I have just 2 assassin snails in the tank so I obviously have 1M/1F. I haven't seen any eggs as described anywhere but there are so many plants that the egg could have been anywhere. Temperature is 74F and it's a tank with 3 species of tetras, if that matters.
They definitely have plenty to eat with so many spiral snails taking over so here's to more babies!

Hi, wanted to bump this topic...
I had 2 assasin snails till a month ago when my flatmate looked after my tank-1 got trapped in the filter (very sad).
They were laying eggs before this.
I recently thought I had seen more eggs but dismissed it knowing I now only had 1.
However... This evening I came home to find an egg on my vallis plant. I only bought the vallis 2 weeks ago.... From a snail free tank and I am sure there was no egg on it yesterday.
Any thoughts?
Thanks

30 l juwel vio, fluval 206 external filter, DIY co2, 50w heater.
Black sand, moomin and bog wood, granite rocks
Fauna: 14 cardinal tetras, 5 boesemani corydoras, 3 otocinculus, bee shrimp, 2 assassin snails (some pond snails for the assassins)
Flora: vallisinaria, have moss, flame moss, mini pellia, fissidens fontanus, Pygmy chain sword, dwarf hair grass, golden anubia, bonsai Anubias and some algae (!)

Could be the females can retain the sperm for some time. So a single female that had been with a male may still be able to lay eggs for some time. Just a guess. But mollies do this and mystery snails do too.

20g L46/hastatus/pygmy corys, 10g OEBTs, 10g blue bees/blue velvet shrimp, 10g CRS, 25g L174s/BNs/L340s, 10g yellow/red tiger shrimp, 15g clown plecos/CPDs/habrosus corys, 15g cory fry, 29g Weitzmani/panda corys/BNs, 46g L134s/salt and pepper corys/BNs/rubberlip pleco, 55g SAE/L201s/L199s/BNs/kissing gourami, 75g L316s/BNs/L134s/CAE/silver dollar, 30g L340s/L211s/CPDs,10g tangerine tiger/snowball shrimp, 20g L134/habrosus corys, 10g CPD fry

I bought a single assasin snail from a pet storge with many in the tank. The single snail laid eggs throughout the tank. I now have at least 1 confirmed assasin baby in the tank. Took a few months for me to be sure it was an assasin until it had enough size, but I am 100% certain they can reproduce by retaining sperm.

I have little luck on breeding assassin snails, the babies just can't survive in my tank.

It's possible that you might have some young individuals in your tank that are just beginning to be able to breed. I hear that they tend to hide in the sand/gravel when they're little and only fully come out (to a degree) once fully mature.

I own two assassin snails, one of which has an almost completely blackish-brown shell and whom I rarely, if ever, see unless its under my rocky overhang. My other one has highly visible yellow stripes and is much more active (I've even seen it feed during the day), so I can attest to adult snails being able to hide.
