Tetra 16623 TetraMin Tropical Flakes, 4.52-Pound, 10-Liter

Q: Is any one else having issues with this new clean and clear water fish food? The food that isn't eaten blows up into spoiled messes in the water

Just like everyone else said, regardless of the food you use you should not overfeed. This is a common issue because many don't know how to feed their fish properly. I often give them a VERY small amount and watch how the consume the food. I then add a bit more once or twice. They do just fine being a bit hungry. Also, I don't feed them more than once per day and I feed in quantities so that very little of the food hits the bottom of the tank. They need to be eager to eat to avoid water pollution.

Q: Can goldfish eat these

Yes, they can eat them, although they would not meet their nutritional needs, properly. We would recommend TetraFin, our diet for goldfish.

Q: Will this stay fresh after opening. I did not realize how big the can was. . I'm guessing I'll need to baggie it?

We have been purchasing the 4.5 pound container with the snap seal lid for years. We transfer the food to a smaller twist seal Tetramin containers for daily use. We have been doing this for at least 10 year (repurchase the 4.5 pounder every couple of years) and fish still are as excited near the bottom of the big container as for the first from the container. Don't worry about it!
