Do not buy it and feed your fish if you don't want your water fully cloudy
This is not a good food for fish, especially my gold fish in my case.
I put a very small amount of this flake food to my 2 gold fish tanks (1 small/medium size goldfish and 1 for large size gold fish) both my tank terrible cloudy on a day after. I have to change 60% water.
What a waste of money and time ! I should stick with API or even goldfish flake food I bought from Coles/Woolworths.
