hey cod...
what you are feeding your flame is exactly what i feed mine. mine devours the brine, spirulina flakes, and the formula.
i guess sometimes fish just dont take to the journey across the world like others. unfortunately we're all bound to run into it if we buy enough fish.
if it dies, all you can do is try another. cause you can lead a horse to water... but you just can't make him eat brine, formula, or spirulina.
g'luck
