Charles,
I’m off on holiday in a couple of weeks but when I get back I’m going to focus on some regular feeding patters and see if I can as you say “persuade” mine to fully open. They are a gorgeous coral when they open. I have seen some great photo from others on the forum so it can be done, its just getting it right.
This is as open as I’ve managed to get them. Taken with old iphone apologies for quality.
This is how I feed them. Taken with old iphone apologies for quality.
I’ve just seen Terry’s thread above good luck hope you get sorted very soon.
