I just recently got back into the hobby after a 10 leave. I bought a 90g full setup from someone locally. They look much better than they did when I got them! What tank depth do they do best in? Currents? Etc.
I haven't found the war coral to be very demanding, it grows very well in my biocube with low light and medium flow and also did well in higher light and flow in my old display.
I’ve been keeping them high in my tank. Think I’m going to drop it down lower and get them out of my power head stream! See if they like it better with less direct light intensity.
