Newts and goldfish are two of the most common pets that people keep in their homes. They both make great tank mates and will get along just fine as long as you are careful to provide each animal with the space they need.
However, it is important to note that goldfish can outcompete newts for food. This can lead to a number of problems.

Frog tadpoles
Tadpoles are a type of amphibian that develops from frog eggs. They are able to live a life of freedom and thrive in ponds as well as on land.
They will metamorphose after about a year and be ready to go out into the wild. Depending on their environment, they can delay this process.
While they are still tadpoles, they will eat algae and other aquatic plants. Once they grow bigger, they will also eat fruits and small insects.
Tadpoles are considered a type of macro-decomposer, which is a class of animal that helps to break down organic material. As obligate herbivores, they can significantly reduce the amount of waste in a pond system. They can also act as opportunistic feeders and aid in the development of biofilm.
Toad tadpoles
Toad tadpoles are carnivorous and feed on algae, detritus and stagnant water. They also eat other tadpoles and frog eggs.
The tadpole stage lasts about two months before they become fully developed, able to walk on land, grow back legs and develop lungs to breathe. It is important not to overfeed them, as left over food will decay and dirty water will harm them.
Female toads breed in the spring, and usually lay strings of spawn (eggs) wrapped around vegetation. They mate with males that they can see near the breeding pool.
Once the eggs have hatched, the tadpoles are about 10-12mm long and are black. They will soon form shoals and begin to grow their hind legs. It will take them about 14 weeks to become a frog or toad, and about 16 weeks for them to develop front legs.
Frog eggs
Frog eggs are a great source of food for frogs, fish, birds and reptiles. However, they can have a bitter and fishy taste.
Some frogs lay their eggs in a jelly-like mass on the water’s surface. These are called frogspawn and when they hatch, the tadpoles become frogs themselves!
Other frogs lay their eggs on leaves that overhang a pond. This way, the eggs are protected from predators on land and in the water.
Some frogs also produce a foamy secretion that they whip up during mating to make a protective froth around their eggs. The froth dries and forms a meringue-like crust that protects the eggs. When the eggs hatch, the tadpoles crawl down the froth and fall into the pond.
Toxins
Newts in the genus Taricha have been shown to have high levels of a toxic substance called tetrodotoxin, which is thought to have evolved as a defense against predators such as garter snakes.
TTX prevents nerve cells from sending signals that tell muscles to move, which can cause paralysis and death. This chemical is also present in pufferfishes, horseshoe crabs and octopi and starfish species.
When these newts are threatened by a predator, they display a body posture known as the unken reflex and release toxins from their skin. This makes them toxic to many of their predators.
Overpopulation
Overpopulation is a situation where the number of people exceeds the space, economic and natural resources that are available to sustain them. It can cause a variety of issues, including pollution, disease and overcrowding.
One of the most important impacts is that it depletes natural resources. The Earth can only provide a limited amount of water and food, so overpopulation has been linked to the exhaustion of these resources.
To prevent overpopulation, we need to educate people about the negative effects of having too many children. We also need to encourage women to plan their reproductive lives and to use safe and effective birth control methods, such as condoms or sterile implants.
