sailfin, my personal favorites. Never fed anything but flake and mysis and brine for the last 4 years. The only algea it eats are when i scrape the top rim of the tank once a week and a sheet of green comes off, gobbles it right up.
Had a mimic tang untill yesterday, when our tank crashed He will be missed, but we will be on the quest to replace him, once the tank is back in 100% action!
