Just like it says. I have limited space in my 3 gal
, would like to but my orange Zoas real near my dk purple zoas, they might touch if they both extend all the way. The reason why is my purple ones have not looked right for a couple days, 1/2 buttons not out yesterday, none out today when I got home, kinda out of the water flow, thought I would move them for a day, the orange Zoas seem happy, so I will move the purple ones beside them.All tank measurements in check,well- PH at 8.1, bumped it up tonight- will check tomorrow. Other than that all is good.
