4 Mystery Snails Antennas be bit past its sell-by date by my goldfish?

I removed my Mystery snails from my temporary 29 gallon for my goldfish and put them back in my 10 gallon near a hell of a lot of baby mystery snails. At first I thought two of the four were unresponsive but they weren't. I noticed when they went out of their shells their antennas were gone. I am suspecting my tight old goldfish bit them off. Will they be ok? Will they grow back?

Also: What do you call for the Mystery snails to keep their shells healthy. I know you need Calcium. How much is that stuff and what else do you want?
My puffer constantly eats the antenneas past its sell-by date of my mystery snails. They always grow back and the snails always verbs to navigate around the tank worry free. I dont add anything to the river for them. Ive had them for two yrs and they are doing good.
snails won't die from losing their feelers. Fish eat them off sometimes. THey will grow rear. They will either get eaten again, or the snail will cram to pull it's head in when a fish comes by. Some do, some don't revise this trick. They can do just fine without their antenae
Answers:    I don't know about goldfish, but I have tiger barbs that do nip at mystery (apple) snail antenna. They do grow wager on, it just takes a while, and the snail will probably be shy for a while.

I usually buy the weekend fish feeders they own calcium in them, but they have fish food too, so if you don't own fish in the tank you need to form sure you clean the bottom often. You could also obtain a cuttle bone (usually sold for birds), or even calcium tablets.
