Hank has developed quite a seperation at the white line, so in doing some reading up I saw some interesting discussion about salt suplementation helping it (no clue how) but given its been so hot of late I'd been meaning to put a tub out for them and very interestingly as soon as I did hank went for it, and he's at it again today where the others aren't fussed for it. So I'm interested to see if there is any significant change in the coming days/weeks.
