An Amber snail, possibly Succinea putris
No interactions present.
Possibly this. Robert Cameron's Key to land snails (Field studies council 2003) shows 3 species that look like this. The other two are:
Oxyloma pfeifferi which 'usually has a dark body', but yours does not
O. sarsii which has a dark amber shell and is "rare and restricted to wetland in E.Anglia", so probably not this either.
