No more than it can die from goldfish flake.

[Whiskas]

why?

[spoon]

i would say if your not spending much money on goldfish food then the goldfish would do a lot better on tropical flake . some cheap goldfish food is absolute crap

[danilada]

I had a goldfish (well two), cycled the tank, tests came up all clear, so brought one home it died about four days later, so changed 50% waited a week, ammonia was a little high when I found the dead goldfish, a week later tests were clear again, then over night goldfish number two died.

Can't put my finger on why, thought it may have been the tropical flakes?

Fish were healthy looking, tank they came from was good with no signs of illnesses etc.

How did you cycle the tank? Maybe the bacterial population wasn't big enough to handle the bio load of the fish.

Goldfish are very messy and produce a lot of waste. I suspect water quality as the culprit.

What size is the tank?

How long, and how, did you cycle it?

I do not understand as you say you had 2 goldfish, cycled the tank, then you say you brought one fish home. I am assuming you did not use these 2 fish to cycle the tank? :-?
