Feed mysis? Poll

[muck]

I usually thaw a cube of Hikari mysis in tank water add a few drops of selcon and feed that for a couple days in a row.
Sometimes I add a cube of Frozen brine shrimp just cause I have it left over from when I had convicts.
I also feed OSI marine flake a couple days a week.

I bought some Formula 1 and 2 pellets to try but my fish don't seem to be interested in them.
