Well, I got my first coral the other day. It was a cultivated toadstool leather, a double one. In the store, one was yellow and one was orange.
I drip acclimated them over 2 hours, and then placed them in the tank (this was on Friday). They didn't look good at first, polyps retracted, sunk down, white patches developing. But after a few hours, the right coral (orange one) expanded and opened its polyps. But the left coral changed colour from yellow to green!
Now, 2/3 days later, I've noticed a trend:- When I get up in the morning, the yellow/green coral has its polyps out, but by lunchtime they're back in and stay in all day until the next (early) morning.
The right one brings its polyps in and out throughout the day, regardless of the lighting, but mostly keeps them out.
Any ideas?
