Food Type[edit]

Fast Sinking.

  • It stays together on the substrate and does not fall apart for a long time.

Date stamp[edit]

The container should have a clear date stamp somewhere and you need to check this. Fish food doesn't last forever, even if unopened, and you will want food that has at least 6 months of life still in it.


All proper, high quality food should come in a sealed container of some kind as exposure to the air starts the decay process of any vitamins and protein. Never buy any that has the seal broken as they could be infected with bacteria.
