Everyone swears by this food, but I can't understand why. My tank smells after using this food, my filter dirtied much faster, and it discolors the water. My first don't seem to really like it all that much either. I really wanted to like this food, but I really hate it. I have an entire unopened bag that I really don't even want to use.
The food does exactly what it says, it sinks, fast. Not as big as I was expecting is the only thing I can fault it for. It does smell weird, but the goldfish like them.
sinking, they are supposed to be slow sinking they sink instantly. Stinking is what my fish tank smells like. They stank up the 20 gallon tank after two feedings. It smells like rotten fish. This food may be ok for an outdoor pond, but i will never use again in my tanks. the fish didnt like it much and the food instantly hits the water and sinks. the food says slow sinking which in English means it takes time to sink, which is false advertising. It should say Fast Stinking!
I've tried a number of fish foods and this is one of the best I've used. Doesn't cause constipation too badly. If you soak it in advance, it's even better.
