Hello! I have a 20 gallon running with live rock, aragonite sand, an AI Prime, and Reefflowers Coral Salt Mix. Right now I have lots of zoas and GSP that are doing great. The only stony coral I have that has consistently done well in my tank is the duncan colony. It is growing super well and I am in love with it's color and movement. I would love to get more but I already have a lot of green in my tank and duncans don't have many options for colors. Are there any corals that are similar care wise that anyone can recommend? Preferably that come in colors other than green and aren't outrageously expensive. Thanks!
