Frequently Asked Questions
How often should I feed my fish?
Most aquarium fish do well with one or two small feedings a day, only what they finish in a couple of minutes. Overfeeding is the most common cause of cloudy water.
Can I feed goldfish tropical flakes?
In a pinch, but goldfish do best on a goldfish-specific formula like Tetra Goldfish Flakes, which matches their digestive needs and feeding habits.
What food brings out koi color?
A color-enhancing pond food such as TetraPond Koi Vibrance is formulated specifically to deepen koi coloration during the active feeding season.
Do floating or sinking foods matter?
Yes. Match the food to where your fish feed: floating pellets and sticks for top feeders like bettas and koi, and flakes for community fish that feed near the surface and mid-water.
Our Verdict
Top Pick: TetraMin Tropical Flakes, the most versatile, top-rated staple for community tanks. Best Value: Tetra Goldfish Flakes, an inexpensive, species-specific everyday food. Premium Pick: TetraPond Koi Vibrance, the one to buy when koi color is the goal.
