IME, variety and quality are the keys to a good diet. I feed every other day, roating between frozen and flake. I feed frozen mysis and marine cusisine, thawed and rinsed and soaked in garlic extrem, selcon and vita chem. I also add DT's, liquidlife marine and kent zoo-plex. For flake I use Ocean nutritian Prime Reef and OSI Spirulina. Nori every non-feeding day for the tangs.
Some people are like slinkies...they serve no real purpose yet can still bring a smile to your face when you push them down the stairs!:p
Have a great day! Brian
