Frozen mysis in morning when lights are out to feed Tubastrea and shrimp. Brine Shrimp Direct brine shrimp flakes or Vibragro pellets in evening when lights are on. Mushrooms, LPS corals, and the anemone are target fed with pieces of shrimp every week or so. Also, occasionally doses with a bit of algae cryopaste.


Front glass cleaned about once a week, and dust and salt deposits removed from covers and lights. Partial water change, about five gallons, every month. Excess algae removed weekly. Corals trimmed as needed. Protein skimmer cup emptied and cleaned when it gets full. Siphon tubes for both the overflow and propagation tray are cleaned whenever they start collecting too many bubbles.


Excessive algae growth in the main tank and a massive flatworm infestation in the propagation tray. Flatworms were never able to establish themselves in the main tank as blue damsel and the watchman gobies were seen to be eating them on some occasions. The infestation in the propagation tray was cured when two Chelidonura varians were added.


Lack of space! Need a bigger tank!
