Hi ChrisI hate to be blunt, but keeping a Goniopora alive for 2 months is effectively meaningless. Usually they appear fine for a few months and then, after 2-6 months in captivity, slowing begin to go down hill and eventually waste away. People say that they are difficult because of the tens of thousands that have been imported into this country, perhaps a few dozen people have had any real success with G. stokesii (the species most commonly available and commonly bought). That's a success rate of maybe 0.0001%, at best.
Based on the few cases of repeatable success that have been reported, and the pattern of decline, the corals are simply starving to death in captivity and thus far it is very challenging to provide them with enough of the right kind of food, where feasible at all. Methods that allow many other corals to flourish simply don't work for G. stokesii.
The only cases of frequent success are with some of the less common species, such as the red one cultured by ORA, and the secret to their success seems to be that they are less demanding of food. Even these are challenging though and I've seen many, many cases of them collapsing in the tanks of even very successful aquarists.
They can be extremely challenging and even if successful, the amount of food that many of the species require, can lead to a tank crash!!!evoIX_Reefer said:So expected decline is at 5 or 7 months? was there any particular reason? or they just call it quits?
I agree tentacles but most people were saying near impossible.
Justin Credabel has worked on them ... you can read about it here and here
I don't know what you are feeding it, but recently some specific food has been or will be made available, do remember that this food is new and Justin has long experience and means that the majority of hobbyists do not have. This specific food has negative buoyancy, this means it will sink and land on the Goniopora polyps ... if the current is not to strong, so you should consider that beforehand, the same applies for any other coral, you have to tailor your system according to the needs of the critters that you want to house in it and not the other way around.
