apple snails in cold water
 
Is it possible that apple snails got cold and died in a colder tank after being transferred? Or maybe they are just hibernating? They hang around or lie on the ground without a move. I am afraid I've lost them.

What temperature is the tank? They should be fine as long as the temperature does not go much below 20 in which case they would become quite sluggish but I think would survive, albeit not in optimum conditions, a little under 20.

I am afraid one is definitely dead now. I took him out today. There are two more - they are locked up in their shells. They may be sleeping. The temperature is 17-20, and this is a tank I have at work. I haven't set up all the necessary things there yet. I thought the snails would just live there without a problem. I have three tanks at home and the temperature is 24-25. I think they felt the difference and unfortunately couldn't cope with it. :cry:

17 is a bit low but I don't think ti would kill them unless it was a quick change in temp.

When snails die they rarely close their shells completely. They are usually open a little at least.

Sorry to hear of your loss.

Well everything i found said that 18 - 28C (65-82F) is ideal so the temp doesn't sound like the culprit. I would be more concerned with the pH and GH if the water. The pH needs to be above 7 and the GH needs tobe high, 5dGH or about 100ppm. If the pH is too low that could explain why they are clamped shut and won't come out because it could be burning their skin. Too low a GH will cause erosion of the shell and eventually cause death if it gets too bad.

Post your pH and GH and we can try to go form there.

Thank you all for the information! I am inclined to think, though, it was not the ph or gh, but still the temp that killed them! I have installed a good heater and a new filter, and put a new snail group in there. Today they all were very active crawling happily around except one who remained shut in his shell. But he had been like this in his mother tank before.

It could have been just the sudden change in temp conditions.

I have plenty of these little guys - they keep producing babies in all my tanks, but I still feel sorry for everyone I lose. Thank you for the support!

Are these "apple" snails laying eggs above or below the waterline? If it is below then they are likely not apple snails.

What is the shape of the shell?

Mirta 10-18-2007 02:12 PM

They are laying eggs above the waterline. In one tank they actually use the lid. They are apple snails, since they look like apples - large and yellow. The whole population of my snails come from a single mom who apparently was bought fertilized.

What was your Ph? And your Gh if you have it?

May I ask why you don't think this could have caused the death?

Well if they are laying eggs that readily then they must be healthy. The biggest problem I have getting snails is my LFS does not take care of them. I had to acclimate my last batch for almost 12 hours because the water from the LFS had 0 GH and the pH was 6.6 I was not happy with them and they still have not started to take care of them. On top of that, the staff told me that mysteries lay their eggs under water and you did not need a male a female. I tried to tell them differently but it didn't work. Since you are doing so well with yours, if you have some extras you don't want sooner or later, offer them up to other members. I have the healthiest snails I have ever seen and got mine for Trishfish.

Mine have been laying eggs like mad recently and I actually had my first clutch ever hatch last night.
