For feeding tropical fish is a flake food and a pellet food available. Both foods contain a well balanced composition based on the feeding needs of tropical fish. Both the flake food and the pellet food are well accepted and pollution of the water is minimised. Colombo advises the use of Tropical pellets for daily nutrition of your tropical fish. Pellets contain more nutrients and pollute the water less compared to flake food.
For goldfish in aquariums a flake food and a pellet food are available. Both foods are adjusted to the feeding requirements of goldfish, which are very different compared to tropical fish. Colombo advises to feed Goldfish pellets for the daily nutrition of goldfish.
