2) never target fed....no phyto ever
3) tank is heavily skimmed for the sps
4) 1000mg/hr ozone
5) 400 watts UV
6) no sand bed to speak of.
7) no additives and no refugium
8) the goni has grown to huge proportions and occassionally drops babies.
I'm not saying that this is the key to keeping gonis (nor am I convinced that a dirty tank is the key either).....I'm just asking, in your opinion, how does the size of my tank (850 gals) overcome these more sterile conditions ?
Hi Steve,
If I'm not mistaken, at least one of yours is of a red/reddish-brown variety, correct? Those tend to be "easier" to keep and I would bet that they benefit more from their zooxanthellae than most other common Goniopora species in the hobby. Also, with an 850g tank, I think there would be quite an enormous amount of sub-visible or microscopic plant and animal life in there even with heavy skimming, ozoning, and uv'ing. Your Goniopora is getting nutrition from somewhere. I think "clean" water and regular water changes is much better for them than "dirty" water though (ie. nitrates and phosphates). If Goniopora thrived in "dirty" water, then they wouldn't be so difficult for most people to keep. On the other hand, I have a pretty massive amount of filtration on my 75g, and if I didn't feed my goni's they would be dead. Deprive them of food for several weeks and they begin to show the effect of it; some quicker than others. I only feed them meaty foods, no phytoplankton; although I'm sure phyto would help the overall ecosystem.
I guess the moral of the story is that when the word "Goniopora" is mentioned, people tend to associate the name with a single coral, but in actuality there are some distinct differences between the species. Some are more sensitive to light than others, some require more food, some are more sensitive to water flow, some are more susceptible to brown jelly, and some are irritated more easily. The specific requirements for each species will eventually get worked out, but the main problems with keeping them will always come from light overexposure, tissue damage, and/or the lack of nutrition.
