Title: Immobile Nerites...
Post by: Aquatot on December 13, 2013, 12:56:22 PM
So, I received some surprise nerite snails on Monday. They're beautiful... shiny shells, healthy-looking undersides. But they haven't moved more than a few millimetres since I got them.

One of them keeps turning over on its back. I'll reach in and turn it upright, and a few hours later it's upside down again, tucked into its shell with just a little bit poking out. The other one has moved slightly more, but not at all since yesterday. I haven't seen either out of their shells properly, and they certainly haven't eaten anything. It's been four days since they arrived.

I've never kept nerites, so I'm not sure how normal this is, if at all. My water readings are fine - ammonia and nitrite 0, nitrate just under 10. I haven't done a recent pH test (which I will get to), but it's usually stable at around 7.6 or so. Soft water (see my earlier post in the General section if this sounds weird).

Any advice, more experienced snail keepers? Are they just taking a while to get used to a new environment, or am I right to be concerned? Anything I can tempt them with? They ignored an algae wafer I left right beside them. I'm getting a little worried about them at this point.

Mine were fond of green beans, of all things. I have no idea what to do for a sick snail... Sorry!

Thanks for the reply, Betsy. I'll try some other veggies. I've read that nerites can be fussy and might not eat anything other than algae... not necessarily the case, then?

Mine ate those goofy snail cookies you make with gelatin, algae tabs, and various veggies I put in there. Are yours in fresh water or in brackish? Do you know how the previous owner kept them? If memory serves, they are originally brackish creatures, and if they have been moved from brackish to fresh with a cold snap in between I could see it being difficult for them.

I got Nerites yesterday and mine are moving. Not very far but they are several inches from where they were yesterday. I wonder if Betsy might be right with the brackish water.

What I've found out is that copper is harmful for invertebrates and some fertilizers contain copper. Mine has very little copper and my big snails seem to tolerate it, but it may have been the culprit killing the crystal red shrimp I tried a year or so ago. Just a possibility to look into!?

I do hope they perk up Tot... they are really nice snails . ..
Betsy is right about them probably being from a brackish environment ..  My LSF gets them in full marine.. they are great in reef tanks. They can adapt to fresh .. so hopefully the will acclimate ..and wake up soon for you .
Other than just not moving is there anything different about them??? .. Body looking shriveled up or oozing out a lot of slime???

Thanks so much, all. I've spoken to the friend who gave them to me (who also happens to work at the LFS they came from), and she assures me they haven't been in brackish water since arriving at the store. I guess they may have been beforehand, but moving them to my freshwater tank won't have been a sudden shock if they've already been in fresh water for a while. She has a few of them herself, from the same place, and said hers also spent several days not moving before they finally perked up. Apparently hers are doing fine now. The LFS in question is only a couple of miles down the road from me, so it's unlikely the water conditions would be drastically different, and I've never had problems acclimatising fish from there.

If all goes well, I'll give the gelatin cookies a try, Betsy!

I ran out of fertiliser a couple of weeks ago, so haven't added any during the last couple of water changes. There are a couple of root balls in there, though, so I'll check those for copper. It never seems to have affected the MTS and ramshorns in that tank, mind you.

I can't see anything else wrong with them, Belinda. The one that keeps turning upside down looks perfectly healthy on its underside... faint pink with a small amount of black body visible inside. It doesn't look at all shrivelled and nothing seems to be oozing. Last time I picked up the other one to look at it, it appeared exactly the same. I even sniffed them to be sure they were still alive in there! No smell at all as of a day or so ago. I don't want to keep picking them up if I can help it, just in case I'm spooking them and making them even less likely to come out...

Hopefully they will wake up and perk up soon Tot..I will be keeping my fingers crossed for luck.

Thanks, Belinda. I did water changes yesterday and took another close look at them both. An hour or so later they'd shifted slightly... one had attached itself to the other's shell. But there's still no more movement than that. It's now been a week since they arrived!

Movement! :happy: Only a little, mind you, but it's something... The one that kept turning on its back (which it hasn't done since I turned it over yet again on Sunday) has moved three whole inches since yesterday! The second one has sort of turned around on the spot and may have moved a tiny bit, but this is the first sign of significant movement I've seen. They're both still in their shells and definitely aren't roaming yet, but I'm clinging to this as a good sign. Fingers crossed for more soon...

Yeah! Good news. Mine seem to move all over within a 6 to 8 inch radius.

Great news!!! soon there will be snail trails all through the tank.


Title: Re: Immobile Nerites...
Post by: Aquatot on December 18, 2013, 01:13:17 PM
I hope so! :happy: Today, the second one (which hadn't moved much) has travelled over six inches to the front of the tank and attached itself to the bottom of the glass! It's been there all day, but that's a huge step. The first one hasn't moved since its brief journey yesterday, but things are definitely happening. Here's hoping they start getting bolder and exploring their new home properly!

Aquatot,

I wouldn't worry too much. I think they'll be fine. Just let them get used to the tank....

tomorrows news from Tot .. I can't find my snail...oops... There he is way on the other side of the tank....  :biggrin:

Thanks, GB. I'm hoping they're gradually getting used to things.

Heh heh, Belinda... I couldn't find one of them this morning!  :woohoo: Turns out it's curled up in a niche of bogwood. The other one is still on the glass where it was yesterday - it's almost like they're taking it in turns to make the next move.

Now I just need to see them eat something, and I'll be happy.

They're not quite zooming about the place yet, but they're definitely getting acquainted with their new home now. I have a huge piece of bogwood in the 55, and they're spending most of their time on it at the moment. Never thought I'd be so happy to look for an aquatic creature and not be able to find it because it's moved from its previous spot. :biggrin:
