average life span of a snail? or why are mine dead?

[SeeCrabRun]

I'm trying to check if this is normal or not.

I have 2 separate tanks and in both I have turbos and nerites that I purchased from the same supplier.

I've had them a few months and all the sudden they've started slowly dying off. First the smaller and now the bigger.

It's been over the past month and it is in both tanks.

I'm thinking maybe they don't have enough food, but I wanted to get some input.

Thanks!

What size tanks? How old are they? What are the tankmates?
No, that's not normal.

1 tank is 29g and the other is 10g. Each tank has roughly the same inhabitants.

1 single damsel fish in each tank, different species to coordinate with tank size. I love damsel fish.
Crabs: hermits in the 29g and a xanthid in the 10g.
Snails: turbo, nerite, dwarf cerith, nassarius.

Both tanks have live rock, no coral. The 29g has a deep sand bed and the 10g has a shallow one. The 10g has a refugium. The sand and rock came from the same place and were split between the 2 tanks. They use the same salt mix. I use RODI water.

The 29g tank is 6 months old, the 10g is 3 months. Water tests fine for the most part, the pH is low in the 10g but still in the acceptable range.

Only the turbo and nerites are dying. The ceriths and nassarius are fine.

I did have a spike of q-tip sponges for a while, they've dwindled but not completely gone away.

Turbos are kindof hard to keep alive if you have a low nutrient system, not sure what your algae situation in the tank is, but if it is low, it is likely that the snails were starving.

Try supplementing with nori and I think i read somewhere that they will much on hikari veggie wafers.

Turbos? I suggest removing any living turbos, those guys are a bit large for nano tanks. They're starving.

I worried it might be they don't have enough food. The tank is pretty clean.

Try feeding your turbos uncooked and unsalted nori. I've had many of them gobble it up.
