Turtles may eat fish, but how often depends on their species and environment.
Aquatic turtles primarily feed on fish, crustaceans, worms and insects as their primary food source.
Feeder fish such as goldfish and guppies can be offered occasionally to pet turtles to provide mental stimulation and exercise while meeting their calcium needs.

They are omnivores
Turtles are omnivores, meaning they consume both plant and animal foods. However, the type of diet a turtle prefers will depend on their age and species.
Land turtles typically feed on plants and plant parts, though they may also eat insects, eggs, small mammals, birds and other reptiles. Some turtles are herbivorous – eating only grasses, weeds, flowers and fruits.
Some aquatic turtles are strictly carnivores, feeding solely on fish. They can be found in fresh or brackish water throughout Africa, Asia and North America.
An aquatic turtle’s diet can include smelt or mackerel. However, feeding only fish may disrupt the balance of essential nutrients in the body, leading to vitamin E and thiamine deficiencies.
They are herbivores
Turtles are omnivores, meaning they eat both plant and animal foods. While their mouths lack teeth, their jaws have broad, sharp edges which enable them to crush mollusk shells with ease.
Green sea turtles, for instance, are herbivores and feed on algae, grasses and seaweed as adults. As they get older however, they will occasionally add meat to their diet when available.
Some turtles are specialist feeders, feeding exclusively on one type or variety of food. For instance, the hawksbill turtle feeds on various varieties of sea sponge while leatherback turtles mostly consume jellyfish and other invertebrates.
Turtles’ differences in food preference are largely due to adaptations in their skull and jaw structure, as well as where they live. Turtles have evolved to feed on what’s abundant in their environment, so it’s essential that they have access to fresh, nutritious food and clean water to promote a long and healthy lifespan.
They are carnivores
Turtles eat a variety of foods depending on their species and where they live. In their natural environment, turtles feed on fish, insects, and other animals.
Carnivorous turtles possess sharp teeth which enable them to grab their prey and consume it whole. Furthermore, their powerful jaws enable them to bite hard sea life such as crabs or lobsters with ease.
Some turtles possess beaks that can easily slice apart small creatures and plants, such as amphibians and carrion. Their muscles can exert hundreds of pounds of pressure to move chunks of food to the back of their mouth for swallowing.
Turtles of all species adapt their diets as they mature, shifting from being primarily carnivores to omnivores. Green sea turtles, for instance, mainly feed on carrion until juvenile size; as adults they switch over to feeding on algae and grasses.
They are predators
Turtles are carnivorous animals that eat both plants and meat. They live in either fresh or saltwater environments and belong to the order Testudines (formerly Chelonia).
Many species of turtles eat strictly carnivorous diets, which include fish, shrimp, crabs, insects, snails, eggs, amphibians and the occasional small bird or mammal. Others subsist on herbivorous meals which consist of grasses, leaves, weeds flowers and vegetables.
Sea turtles are especially vulnerable during their nesting season to terrestrial predators such as opossums and foxes. Other wildlife like otters, weasels, minks, fishers, and badgers will take notice of hatchling turtles, eggs, and nests to try to consume them.
Turtles can retreat into their shells when threatened, so it is essential that we provide them with safe spaces and shelter when predators are nearby. Even if the predator isn’t trying to eat the turtle, even minor injuries or deaths may result.
