Newts are aquatic amphibians that need an ideal aquatic habitat with clear waters, ample hiding spots, and clean environments in which to thrive. A large natural wildlife pond with plenty of hidden spaces will help ensure they can escape predators lurking nearby.
Newts that encounter fish typically exhibit avoidance behavior such as reduced sexual activity and shelter-seeking strategies in response to predators, including reduced sexual activity and shelter usage. Unfortunately, such strategies can be costly as they interfere with essential activities like breeding.

They are warm-blooded
Goldfish are ectothermic animals, meaning that they do not generate their own body heat and therefore rely on the environment to regulate it. Furthermore, they feed off both plant life and animals for sustenance – something newts should avoid doing! As goldfish have no problem preying upon newts.
Newts need an aquatic habitat with clean water and plenty of hiding places in order to feel secure, while goldfish prefer more active environments; their presence could disturb the newts by digging up their plants or moving around in their tank, potentially leading to stress for all parties involved and necessitating separation between species. It is therefore not advised that both species cohabitate in one tank.
If you decide to keep newts with goldfish, ensure the goldfish are large enough not to consume your newts. Fancy goldfish tend to be slow swimmers that won’t bother the newts too much while Shubunkin or Comet goldfish could quickly catch and consume your newts. Goldfish may also reduce the number of hiding places available to your newts; therefore, for optimal results it would be wiser if they were kept separately in tanks.
They are nocturnal
Goldfish are nocturnal animals that sleep during the day and come out at night to feed on both plant and animal matter, including algae, insects and small crustaceans such as crabs. Their diet also boasts high amounts of protein. Goldfish are skilled predators; when hungry enough they may chase after newts that move quickly or display sexual behavior.
Goldfish require plenty of quality sleep in order to strengthen their immune systems and ward off diseases. Because they do not experience REM sleep while resting, no physical changes occur while asleep. Signs of sleep deprivation in goldfish could include acting lethargic or showing symptoms of Swim Bladder Disorder – although yawning alone should not indicate sleepiness; rather it indicates clearing of their gills; any fish laying sideways indicates illness instead.
They are predators
Goldfish are omnivorous creatures, feeding on insects, frogs, small mammals and even newt tadpoles. When kept as pets in captivity they consume earthworms, mealworms, crickets, daphnia and blood worms; in nature they prey upon fish, birds, reptiles and amphibians in addition to preying upon predatory fish such as herons or egrets in shallow waters with unprotected banks for breeding purposes – or four legged predators such as raccoons can become a problem when kept near garden ponds.
Goldfish have ultraviolet vision that allows them to spot food and predators by reflecting off of water surfaces, while their lateral lines detect currents and ripples to detect food sources and obstacles underwater. Although this might translate to behavior in an aquarium environment, its outcome remains uncertain.
They are omnivorous
Goldfish are omnivorous fish, meaning that they eat both plant and animal matter. Their diet primarily consists of crustaceans, insects and various aquatic plant life found in ponds as well as algae and other microorganisms; thus resulting in an effective digestive system capable of processing both nutrients from plants and animals.
Goldfish are great at filtering food through their mouths using hard plates called pharyngeal teeth that allow them to grind and crush food efficiently while filtering out gravel, bits of plant matter and other materials they don’t wish to consume.
Although keeping newts and goldfish together may seem like a good idea, this should not be done. Many species of goldfish are predators that could prey upon newt eggs and tadpoles if kept together in one tank without enough cover and fresh water for each animal. If keeping newts with goldfish together is something you decide to pursue, ensure each has ample cover as well as ample water supply.
