Care for soft corals?

[hyrumbradshaw]

What is the necessary care that soft corals need? I have a 30 gallon tank with power compact lighting they are not looking as good as they have in the past, I mean they dont look bad, I have some zoos, xenia (i dont think its pulsating), and kenya tree, and green star polyps.

Should I bee adding things to the water or some type of food for them?

It's amazing how many people ask questions like this. It's similar to someone asking, "My car is squeaking. It's a Chevy. Any ideas?" It is a valid question, but the possibilities are so numerous that it is impossible to answer without more information.

What are your:
- Water parameters (temp/pH/Ca/Alk/NH3/NO2/NO3)
- Lighting (you said PC, but wattage, bulb type?)
- Filtration (mechanical/chemical)
- Pumps/circulation
- Sand bed depth/type
- Amount of rock
- Feeding schedule
- Supplement schedule

Then, when you say "they are not looking as good as the have in the past", what do you mean:

- Dying/necrosis
- Color change
- Polyps not opening
- etc.

That all said, given that all of your corals are photosynthetic I would first look towards lighting and water quality issues. Of course I can't get any more specific until you provide more data.
