The story now, reading clockwise from the front:-
The 3 replacements, one almost hidden by the big 'un.
One I added to fill an existing gap & surround the Kingfisher.
A "Countable" live 7 with; I know not how many passed on & a tiny one starting to show.
"And finally Cyril"© One I used to replace an earlier one suspected dead at purchase.
All thriving I'm pleased to say.
