Gary, I may pick one up myself next week and proof the pudding, as it were. With gorgonians in general, we are really just starting to scratch the surface. We need to forget some of what we have learned with stone corals and consider why animals such as the gorgonians and azooxanthellate soft corals have conquered their niche. As we see them together with the stone corals, they must not create a direct competition, rather expand the limits of the environment. In other works, what the zooxanthellates do with zooplankton and symbiotic algae must be coverd via a non-competitive feeding strategy. Katharina Fabricius' evidence that many soft corals are actually planktavores opens a whole new window. Clearly, many members of the NPC are not relying on their stinging cells to capture and hold their prey. Being able to identify this quality in an animal may simplify its feeding regiemen.
One aquarist that has been holding this Acalycigorgia for over one year related the following tank parameters:
PO4 - off the scale, it is so high! This is still questionable, as he keeps Acroporas in the tank as well. It may be a constant flux of phosphates through feeding that keep the reading so high.
NO3 - 20-50mgl
Current 5-7cm pS, over this rate it does not feed well!
Miracle Mud filter with weak skimmer.
Stands in shadow with only indirect light.
The animal is fed mornings and evenings 4-5 times with a mix of cyclopeeze, lobster eggs, UltraClam, UltraMin F, UltraMin S, being changed in mixture to give a varied diet. Various vitamins and aminos are used on occaision. The two main ingredients are cyclopeeze and UltraClam (both of which I use, along with the new Ultra Sea Fan, plus Timo foods). He feeds 1ml of the mix in 20ml of water and injects it into the current before the animal, in small amounts.
He has had growth, as well as polyp bailout in the year and the animal has not degenerated. He will be reaching the 2 year mark this Spring! Something he mentions is that, if the animal does not open its polyps after a few days, it is very hard to get it back into form. This may be the main reason we have so few successes. The animals are half starved when we get them and cannot recover.
When I hear more, I'll report back.
