Sick Snail?

[sw65galma]

The other day I found one of my turbos in the middle of the tank upside down closed up.
So I poked at him and flipped him over.
He opened up moved around a bit and closed up.
I left him for a day and he was still in the same position the next day.
The next day, I pulled him out, thinking he was dead and as i was moving him he came out again.
I held him near the glass he sort of grabbed on to it, but not enough to hold himself.
After a few attempts I left him on the live rock where he's just moving a little bit.
I'm not sure if I should remove him from the tank or leave him be and just check everyday to make sure he's alive.
Any Ideas would be greatly appreciated.
The water Parms are correct, the other 6 Turbos are fine, there is Plenty to eat..
This is a 65 Gal 4 month old tank.
PH is 8.2-8.4
Salinity is 1.022-.024
temp is 80
Nitrite = 0
Amoninia = 0 and high has only been .25
Nitrate = between 0 and 40
Currently has 10 damsels
7 turbos
3 Peppermint shrimp
2 Emerald Crabs
35lbs of LR
Any Ideas?
thanks

I check him today, he's still moving...only when I pick him up though.
Otherwise he stays wherever I leave him.
Damsels I have
3 - Domino
3 - Chromis
2 - 3 Stripe
2 - Yellow Tail.

Is you tank producing enough Diatoms for this many snails? Just a guess on my part. It could just be starvation.
Copper will also produce those symptoms.

The diatoms is a possibility i guess.
The tank is in the middle of a nice alge bloom on the glass.
it's a brownish/yellowish,green type of spot alge.
Definately not Cynobacteria.
There is plenty of "stuff"on and around the tank..
Weather it's thier choice of food or not is another story.
I don't think it's copper as I would suspect the shrimp and crabs would also be affected and also the other snails.
Is there another test that i am not doing that I should be? (see in orginal post)
Thanks again

If there's a light dusting of Diatoms on the glass every other day then the Turbos will have enough to eat. That's pretty much all they can eat.
Copper affects Diatom munchers like Turbos more than other animals for two reasons.
1 - Diatoms adsorb a small amount of copper when it's present.
2 - Copper ions adhere to the glass & rocks in the tank and that's where it builds up. Diatom munchers scrape Diatoms using their Radula and pull off this layer of copper if it's present.
If you're using tap water of water containing small amounts of copper then Astraea Snails will have shortened lifespans.

Turbo snails belong to the Genus Astraea. They all have similar requirements and habits. The only thing that varies between them is their tolerance to different temperatures.

I got a test kit for copper and it read .05mg/L
I have some coppersorb on hand just in case it was too high.
Phosphates are off the chart, i got some phosphatesorb too.
That snail in question was found dead today, omg the smell!
I see another one that isn't looking good.
it's only half holding on the to glass with it's foot.
Any ideas?
Help before I loose all my Snails!:help:

I don't know the conversion (sorry) but anything over 0.0006ppm is considered too high. This is normally below the detection limit of most test kits.

A Turbin Snail of some type.

The common name for that snail is Turbograzer. It was coined (and copyrighted) by Roger Bull in the 80's. He held exclusive rights for 7 years on the import of that species from Mexico.
Most of the snails I've seen referred to as "Turbo" snails have actually been Astraea. I guess that's the problem with common names.

So you're only supposed to have 1 per 20 gallons? How come the reef package offeres 20 of them for a 20-55 gallon tank? I just ordered the package yesterday.

I am experiencing the exact same thing with my snails. Please share anything you find out. Could it be nitrate levels? How high of nitrates can sanils withstand. My nitrate level is currently around 20. Could this be contributing or the cause?
