Squishy said::notsure:
I learn by trial and error and research. Many and I mean many corals can live side by side(oh I feel the comments on this are comming) Some can even benifet each other. Of course use common sense if the coral has 6 inch stingers don't put a coral 2 inchs away. Reseach is the best and of course this is not a science try stuff let people know it worked for ya and if it didn't work don't try it again. I totally agree with you here , no need for flaming in my eyes. I have lots of corals touching each other in my 210, with no problems. I must tell you squishy that is a great looking tank that you have there. :joy:
