I've got a 30g set up. It's been set up for about 5 months. It inhabits the following...
Fish..
1 bangi cardinal
1 coral beauty
1 black & white clown fish
1 damsel
A few snails and hermit crabs
1 cleaner shrimp
1 sea urchant

Corals..
Finger leather
Candy cane coral
Green leather tree. I don't know it's actual name
And a few kenya trees..

I'm writing this post in hopes that someone can help me with my kenya trees...iI believe they are either dead or trying to die. I've had my water tested and nothing is wrong with my water it's perfect. I only run my lights around 6-8 hours a day.

They just look a little grumpy to me. Assuming your parameters are in fact "perfect," (no spikes of any kind) just give them a day or so and they should bounce back to normal. GL.
