Premium Tilapia Fish Feed (Powder Large pellets) (1kg-5kg) - 5kg / 3mm Pellets 35%

Small fish require more protein in their diet than do larger fish of the same species, therefore more protein is included in the diet of the smaller fish, thus in the smaller feed particle sizes.  Feeding large fish on small pellets will therefore also result in unnecessary protein in the diet, which translates directly to financial waste as protein is expensive.

How do you know then what the correct pellet size is for a group of fish?

There is no one-size-fits-all type of solution due to the divergent dietary strategies employed by different species of fish.  Predators tend to subdue and swallow large, infrequent meals whereas detritivores and herbivores are more inclined to nibble continuously.  It is therefore necessary to consider the behaviour of the species you are farming with in determining the most appropriate pellet size.  However, the principle is that the feed particle must comfortably fit into the mouth of the fish.  Practically, the pellet should be between to of the area of the gape.  Ensure that the fish can comfortably eat the feed being fed..
