Hi everyone, I'm about to pull the trigger to get some coral for my 15 gallon tank I started. I have some zoas in my tank alr that are chilling. I've been looking into what I wanted to add into it and found some that are in the picture beside my tank photo. Just wondering on if my choices are good for a beginner and where I should be placing them to prevent stinging and or blocking from future coral. Besides that any suggestions on what else I could add in the future and where I should place them would be helpful. I'm also thinking about moving the zoas I have currently all together so they would be separated from stingers. Ty to anyone for suggestions
