I feed a minimum of 4 times daily, preferably 5-6x daily. 4 of those meals include frozen PE mysis or Rod's pacific plankton, and 2-3 include TDO and NLS pellets. The tilefish, along with pretty much all the other fish (especially the planktivores) also really enjoy frozen capellin roe once daily, and the reef breeder formula from Rod's food. Frozen food is prepared the night before and thawed in the fridge, soaked in selcon and sometimes vita-chem.How often do you guys feed your tilefish? I saw that second link above recommended 3x a day, but that was news to me!
We also regularly add live rotifers about once weekly, live freshly hatched baby brine about 3-4x weekly, and live copepods every couple weeks.
A varied nutritious diet fed 3+ times per day makes all the difference with these guys and a lot of other planktivores. My chromis don't fight, my fairy wrasses are growing extremely fast and don't fight, the firefish are bold, and everyone looks amazing health and colorwise. And I have multiple fish spawning with zero aggression.
