I hope it has bounced back. With moderate-strong lighting and water current the tentacles expand and swell. I try feeding it a variety of food and hope it stays healthy and grows.
Thank you it does look like and elegance coral when open.
It's in the centre of the photo, it came attached to the small pink/purple/green rock.
Also the other green weed/seaweed on bottom left grew on its own (not sure if its a problem weed)
Bought today but not sure what it is exactly. Each tentacle has been about 0.5cm long but now that it has been in the tank for a few hours with water currents they seem to have gotten longer about 1cm long as they sway around.
The bag waters pH was 8.8 (my tank is around 8.2) so not sure this...
