i see acro/sps on top, acans on bottom. Lets start with your overall goal. What are you looking for in longer run? Which ones are your favorite corals, what growth pattern you are seeing.
I would start with few broad guidelines..
1) evasive, encrusting hard to remove species should be isolated.
2) Coral aggression is a big pain in longer run. So locating them in a way that the natural rockscape and shading from each other control their growth is a good strategy
3) Looking at how its currently, its not bad, pretty classic mixed reef style. I'll need a close up pics with major corals in each region and their growth speed for more specific recommendations
My goal is to have a balanced tank with more sps in the future if i'll still have space for them. I'm quiet worried that i've got too many corals at the moment... Here some. Pictures, had ome troubles since i started the thank in august, some of them really looks bad but they stopped the regression so i hope they will get better... Many thanks
Here some pictures
Can i put the red montipora on the right or left side of the thank where the light is not too strong or is it better where is at the moment? I wuold like to put all the acans in that rock where at the moment the montipora lives. I can even put the montipora a bit higher in the same place and put the acans under the montipora but one it will grow i can't put any coral on the bottom, right?
Look up your corals online, there is plent of info on what each ones needs are for flow lighting and placement and aggressiveness. you have a wide variety. Most coral vendor websites have a care listing on them.
