Sorry no posts for a while. Tank seems to be doing well. Parameters are good but I need to boost the calcium. Current livestock: 2 clowns, 3 PJ cardinals, 1 yellow tang, 2 sharkface gobies (1 living in the overflow) green bubble tip anemone, feather duster, xenia, red mushroom, green mushroom, zoanthids, 2 sally lightfoot crabs, 3 porcelain crabs, 1 emerald crab, and a bunch of nerrite and nassarius snails. The xenia's been around for a month and already split. The red mushroom is sprouting a new head on one side.
Only problem area is the tang. He has some black spots on him and looks like he's rubbing against the rocks. The goby is picking at him but not sure it's helping. Any advice?
