Thank you very much for your support!
Mark,
hopefully I understood, what you're talking about... My bad english...
Unfortunately, I cannot answer what I understood in one sentence
I think that in SPS coral reef keeping there is not the one design, "Hardscape" or whatever Takashi Amano related Freshwater designs call it.
Here, also the Hardscape is growing ;-)
IMHO it is not possible to prune all Coral types as heavy as you can do it with most plants.
My approach is to cut back fast growing coral and raise some cuttings in a different system in the basement. When coral gets ugly from the pruning, I take out a "larger then buyable" colony from the basement system and replace it with the old one. Maybe more than one.
Not so easy cut back coral like LPS or different table-like Acropora or flat growing,
"overcrusting"? ones, demand other reactions, like trying to reassemble them with other colonies to a new element.
All the "Takashi Amano", or better japanese gardening placing rules and tricks apply here ;-).
Interesting studies possible, different coral fighting each other or not,
growing speed, overgrowing capabilities, etc..
Smaller or nearly shadowed coral are moved into the basement system to grow and maybe get a new place in the main tank in the next years.
Btw. the more I change my garden into something japanese garden compatible,
the more I tend to remove rock structures again, achieving something like a reef near the center of the tank. Standing free with air.. aeh water to breathe around. This "negative space" thing etc.. I will for sure further reduce the structures left and right in size.
The left one will be smaller but quite high, the main reef the biggest and a little back and the small right pole will be about half its actual height.
Hope to gain depth with that. Getting more depth is imho quite important.
Looking at a larger element, with having 3 coral species in 3 different sizes, larges in front, smallest far away, fakes a deeper view, over accenting the "vanishing point projection"? etc. etc.
Overall, there have been more smaller pillars with smaller coral in the past, changing to one large, supported one in the center with larger coral on it.
Some pillars are removed, some grown into each other for that.
The biggest fish (Siganus magnificus), as it gets older and bigger, tends to live near/in the big cave, formed under the coral between the former pillars.
I always wanted to keep a Naso Lituratus, but haven't got one, because of the scale thoughts. Really big or too many fish would destroy the overall effect imho.
Sorry, got carried away by this ;-)
