Tetra Tetramin Tropical Flakes - Complete Balanced Diet for All Tropical Fish | Promotes Healthy Growth & Vibrant Colors | Ideal for Freshwater Aquariums & Community Tanks

I have used this fish food for quite some time without any problems, however on receiving my last order we noticed that the fish just would not touch it and all the food was on the bottom of the tank. Subsequently my Parrot Fish lost their colour and looked almost white when they are normally a love gold fish orange colour. On the 2nd day we came to find one of the fish had died. My husband immediately cleaned the tank, changed and purified the water. the fish where still very pale for a few days after. We have since bought another brand of food and they are now thankfully fine.I have used Tetramin successfully for many years, but I recently bought a new tin and my fish are ignoring the flakes instead of avidly gobbling them up as they use to do.I have seen similar comments by other reviewers on here but I didn’t believe them until I experienced it myself. I wonder if Tetramin have changed the formulation in some way? I any case I am now looking for a new brand to replace them.My fish love this food and it does not create dirty tanks as quickly as other food brands I've used. Fluval/Hagen brands are the worse for creating algae. Overall 10/10Great fish food. I use them to feed my Koi Angels, Guppies, Cory Cats and Rams. It hasn't discoloured the water or fish.Doesn't take long to soak and fall from the surface but I generally presoak them anyway along with some bloodworms or other tasty treat.The fish food made my tank messy. My fishes didn't like the food . Clogged the filter. Would not buy again
