Hi, I have acquired 7 rather large GALS, the previous owner told us that when she rehomed them they were in a bit of a state, basically their shells were falling apart, splitting, flaking and some having holes in them. She seems to have done a good job in turning them around, but told us there is still quite a bot of work to do on them. Firstly, they didn't seem to have any cuttlefish in with them so were only getting calcium from certain foods they were eating.
What I really want to know is is there anything I can do to speed up their recovery? As you can see in this pic, one of the shells is pretty rough, has obviously lost a few layers and is in major need of repair.

Is there something I should put on the shell to help strengthen it at all?
Also could anyone tell me what species of GALS these are? I can't seem to find ones like the second pic below with the white end of the shell? Didn't know if this was maybe to do with the fact they weren't looked after properly. I just thought they were Achatina fulica...


Thanks for any help x
