I've noticed that when I put food or anything else in Isaac's tank he doesn't really react in any hurry, but when I put dog biscuits in he goes straight to them, no matter what he was doing or eating.
I'm guessing it's because he can smell them? But I looked at the FAQs on the main site and it says they're not sure if snails can smell.
Does anyone else see evidence of their snails using their 'noses'? and any idea how they might smell?

They have chemical receptors all over their cephalic tentacles (lower ones). These are incredibly sensitive allowing them understand a wide range of smells and tastes and to locate food from a considerable distance away. I'm not sure if this is the same as human "smelling" because ours is based on molecule vibration apparently (perhaps all chemorecepting is) but you'd be splitting hairs arguing that is wasn't smelling.
The FAQ needs rewriting. You'll notice it is drawn from other sites FAQs and was put together in the site's infancy. I've been organising the info for a while now, and including replies to questions I have been asked. I have a lot still to do that I never seem to finish these days, but I'm hoping this thing should be fairly easy to constuct because the information is now there.

thank you - that tells me a lot about his reaction to the different foods i'm giving him then!
and the faq's have been really helpful, i wasn't complaining, just wanted to understand better.
cheers
