I have kept these for several years and they are doing well. I do not add any
any 'unknown' supplements. I have been adding calcium and iodine for about
8 months and strontium for about 3 months. I have the elegans in very
intense light with about 6 inches of water over them. The tank is lit by
4 175 watt metal halide lights.
I moved one of them when I removed the gravel from my tank and
changed from 4 160 watt VHO flourescents to metal halides. He was doing fine
on on the bottom of my 125 gallon aquarium.

Leather corals don't need to be fed. They can get all their nourishment
from photosynthesis.
The tubastrea should be fed at least
weakly. Frozen brine shrimp which has been thawed in salt water and drained
to remove the nutrient laden water works well. This coral will slowly die
if it does not get some sort of plankton substitute.

I have had an orange sponge for 2 years and it is growing ever so slowly. It
is kept in the dark under some rocks.

The book is brand new and hot off the presses.)

Clams need lots of light.

Prefer not to be in extremely strong light, from everything I've read.
They're hardy as all hell; I have two, and they take all sorts of abuse.

Mine absolutely loves the lights. I have one that sits directly under
a 400W MH, and it couldn't be happier. (_Catalaphyllia jardinei_)

Cup corals require frequent feedings with things such as live brine. I've
heard that if you feed them daily, they will grow at a remarkable rate.
Very small pieces of shrimp, etc, might also work, as well as frozen invert
food. Leathers don't require the same feeding regimen.

Yeah, as little as possible. It may also require feeding.

They need light. (_Euphyllia ancora_)

Green star polyps, if my memory is not failing me. This would be a good
one for your tank.
BTW, the scientific names are all being done from memory, so all spelling
flames will be directed to /dev/null. Misidentifications are entirely my
fault, and might teach me a lesson for talking without verifying my facts
first. Then again, maybe not.
(Exception: Don't bother to tell me that elegans corals are _Euphyllia
picteti_. The Mills book and the Manual of Marine Invertebrates both
lie about this one.)

These corals will open their polyps at night and extend tentacles out in
search of food. That is normal behavior. Most non-fleshy stony corals ex-
tend their tentacles during the night. The polyps fold over or close during
daylight hours. This allows the symbiotic algaes to receive light.
You should see the outer membrane during the day which is stretched out
covering the coral skeleton. If parts of the skeleton are visible (ie -
white calcium structure) than the coral has receded a little. You should
watch the tentacles at night and guard against any coral to coral battles
due to tentacle touching.
My red Favites sp. receded in one spot where an Euphyllia ancora stinging
tentacle touched it. The F. sp. was moved away and has completely recovered.
The E. ancora is still extending 4 inch stinging tentacles in the area which
previously contained the F. sp..
