I take the easy way out. I bought a 1 gallon plastic critter container at my LFS and a cheap 5 buck air pump. I buy live brine at my lfs every Tuesday night when he gets his in take it home put it in my container with new SW at about .1020 salinity and it lasts me a whole week. Yes Brine is like candy to a fish, not that healthy , but it sure gets their attention. It is the best thing to start new bought fish off on and get them eating before you switch them to better foods. I use the brine or my live blackworms as treat foods along with normal good foods such as Formula 1 & 2, Angel Formula, Trigger Formula, Mysis Shrimp, Krill, Squid, Silversides, Life-Line Green, Beef-heart all rotated from day to day (I have said before my fish eat better then I do).
