Mostly a variety of things..Phytoplankton or DT's, cyclopese really brings them out if they aren't looking to well a couple of times a week, and I make some stuff up also lots of reciepes out there if you make you own mush...You can do a vegey varity or add see critters to it in a blender. (clams, oysters, shrimps brine shrimps etc) vegey pack mostly anything high in beta carotine, blend it prttey well there might be some chunks of brccoli, carrots, romaine lettuce, things like that but the tangs will go nuts on those usually...I relly do keep cyclopese all the time for sure about 6 bucks for a small tub a Cap Bay...They usually have DT's for around 13 I think last time I was there...Mostly a variety on all my tanks
Check around you might even make up your on...a google search should list many
off to work
Nothing other than what ever the tank gets. No direct feeding. But I feed the tank twice a day, mysis, zooplankton, cyclopeeze, and flake. Or what ever else I have. I mix it daily so they don't the same stuff everday.
