My neon tetras have grown noticeably faster since switching to this food. Their colors are much brighter and the water stays cleaner. I’ve noticed less fish waste in the tank.

Good for small fish under 4 cm. The fish seem more active and their fins look healthier. The color improvement is subtle but visible over time.

I’ve used this for three months now. My guppies are growing steadily and the tank water is much clearer. The probiotic effect is clear and the food is easy to mix.
