My guppies love it. It doesn't have a particularly strong odour and doesn't cloud the water.

The flakes seem to be different from Top Fin Tropical flakes, these ones are uniformly greyish and there are thicker bits. Thankfully the bloodworms in the mix are broken up a bit - full-size they're a bit big for guppies!

The container is very nice - it has a variable size opening. When you open it at its lowest size, it meters the food out very slowly. You can even invert the container completely and nothing will come out until you give the container a tap.

Unfortunately the reason it does this is that the flakes are so large they block the flow of material out. You have to break up the flakes to get them to flow. You also have to break up the flakes so the guppies can eat them!

This is a LOT of food, it will feed guppies for many, many months or even a year or more.
