Hi folks. Still new to keeping corals- roughly 2 months now. Tank is 60 gallon DAS aquarium with in tank box filter (back left). I have a Maxspect Razor 16,000k light over top. Jeabao Wavemaker on the left, filter return on the left facing right, a korelia 750gph in the back facing front, and a Aquaclear canister filter running as a phosphate remover pushing, on the right side pushing flow to the left. I have a few fish, maroon clown who is now 12yrs old (up until 2 months ago my tank was a fowlr), a Lemon Peel angel, royal gramma, orange spotted goby and two cleaner wrasses. Clean up crew are a few remaining blue leg hermit crabs, tuxedo urchin, 12 yr old sea cucumber, bunch of snails and a cleaner shrimp. So I have a xenia colony on the left rock structure, protected from direct flow, on the flat top. It was doing pretty good, growing and then all of a sudden its shrinking and shortening. I have a green montipora capricornus on the right tower that is growing constantly, doubled in size since I got it. Not sure why this is happening, especially since i keep reading how much xenia's grow and are a nuisance and that sps are harder to keep. I appear to have the opposite problem. My parameters are good, calcium is a little low, supplementing frequently and should be back to normal shortly. Everything else is good.In the photos you'll see some algea, but it's a million times better than before bc when it was a fowlr, I let the algae grow on its own. So is it a placement issue? is it too far from the lighting? something else? A little frustrating for me, I really love the xenia coral and how it flows and pulsates. Any insight would be great!
