Rainbow fish questions

    I have recently lost one of the dwarf rainbow fish to an untimely death. I would like to add some more after I recheck the water parameters. Does anyone know how many I should add so they can school? I have a 47 gallon aquarium with the following:
    1 angelfish
    1 blue guarami
    4 black skirt tetras
    3 dwarf rainbow fish
    1 black swordtail
    3 assorted cories
    1 bristlenosed pleco
    Sometimes I notice that the rainbow fish do not like the flakes I put in, can anyone suggest something I can feed them that they will eat.

    I think 3, maybe 4 more dwarf neon rainbows would be good. I have 8 (2m/6f) in a 45. I do plan on adding another male.

    I haven't found anything they won't eat...

    Sounds about right. Rainbows have very small throats so some times it's hard for them to eat regular flakes. I have threadfins and I crumble some of the flakes up really small.
    So it may not be they don't like your flake but can't eat them easily.
