i have noticed that if you truelly want them to pop, have that amazing skirt & that bright orange/yellow pattern to come out, position them within the upper 1/3 of your tank. they thrive under strong lighting & under the right perams, they grow like weeds. they end up looking amazing. here is a pic, i took a couple of months ago. now they look 10 times better & have doubled, to the point of having more orange than green. good luck & happy reefing!
