The back end of hell.
Hi,

I recently bought a bunch off what i beleive to be pomacea bridgesii (Spike topped applesnails) to produce snails for my crayfish tank once set up.

Two of them where at it yesterday, for that long they did a lap of the tank while adjoined to each other.

Last night i covered tohe tank to keep to the correct photo period for them to lay eggs, what i think to be the female then left the water and began producing what i thought to be eggs. I could see small round balls of the same colour as the snailon its body at least.

I camedown this morning to find absoloutely no eggs, and the said snail upside down on topof my sponge filter. I picked it up and placed it on the botton of the tank, assuming they must not lay their eggs the same night and it was struggling to 'self right' due to the texture of the sponge.

Anyhow, 2 hours on it was still in the same position that i placed it, so i picked it up and touched it's foot to see if it retracted into it's shell, it did not.

I put it back and placed a 'veg' tablet next to it, it hasnt moved for it. It is still alive as it's feelers seemt to be moving, and it does not smell of eggs.

Any idea of what the problem could be?

I suspect water perameters may be an issue as the filters are recently established, however the danios seem to be in good health, and i would assume that they would not attempt to breed if the water was foul in the first place.

A water test is not availiable to me for the next couple of days as at my LFS they have the 'bad' staff member in who doesnt know how to trun the tests, the manager is not back in till later in the week.

Any advice as to what is happening here would be great, i have found limeted info on these snails breeding online, and nothing that indicates wheteher this is normal afetr mating, or even if they are supposed to ttry and lay eggs so soon.

Thanks for reading.
 
I should point out that i have been doing daily 20% water changes since i added them.

It still hasnt touched food but had not retracted into it's shell, the other snails look fine and have shown so signs of odd behaviour.
 
How long did they mate?! Keep the female separated from everyone ASAP. A breeder trap will do it. She needs a break.
 
Well over 6 hours, i noticed mid way through the day cycle and they did not stop until lights out.

It would be difficult to give an exact figure, quite epic for a snail!

The other snails have left her alone today.

You think putting her in with my betta and shrimp would be a bad idea? i know the water is softer in that tank. (tank composition is different to what i have listed in 'my tanks' now)

Other than that i could maybe sit a tub within the snail tank fixed tothe top?
I have no specific breeding trap, i didnt realise i would have to seperate snails after mating like some fish.
I also have a massive storage tub, 60 gal, but no lid or spare filter if this would be any good filled with used tank water?

Which would be the best option, i dont want to stress her out and risk killing her.
 
Well i put her in her own tub, just come back after a few hours and am fairly sure it's dead :(

Trap half open, no sign of movement, doesnt smell tho. how can i prevent this happening again?

Surely i dont need to determine the sex of all the snails and moderate how long they spend with each other?

Any links for breeding info are welcome, all i seem to be able to find is info on where they lay, and how long to hatch, not the actual mating process.

Thanks
 
Get a tub and keep her there. Until she smells badly, I wouldn't throw her yet.

And keep the male separated for the time being. Leave the rest alone unless they start harassing the females.
 
The female was somewhat smelly when i got home, so it's too late for her.

Have done as you said with the male, he is in the betta tank for now until i can decide when it is good to put him back, maybe indefinately given i dont know when he is deemable as ready.

Is there an 'ideal' M/F ratio or something that could prevent such things happening again in future?

Really disapointing that it has gone wrong, i dont take too well to making a fudge of things,

I want to get things right second time round for sure.
 
Usually, it's better to have more females. There's no fixed ratio. I had a male that keeps focusing on the largest female and when he fractured her mantle, that was the last straw and he got separated for a few weeks.
 
Cool, thanks for the info.

Last question i promise,,

Is it bad to mark the shell somehow, maybe pencil/marker or something so i can keep track of whats what and who's who? It's a royal pain in the butt keeping track of them by written descriptions.
