Do Fish Eat Tadpoles

Do Fish Eat Tadpoles?

Do fish eat tadpoles? Yes, they do. Many fish can survive on frogs and tadpoles as a dietary supplement, although there is little you can do to prevent it. A tip I recommend for pond owners is to put some stones at the deep end of the ponds to allow them to hide from predators. This allows the frogs to hide away from predatory fish and give them a fighting chance of survival.

How do I stop tadpoles from being eaten?

The best way you can intervene is within your pond give them somewhere to hide. This can something as simple as piling some rocks into one shallow area of the pond. Place these in such a way that it is difficult for the fish to enter and far less likely to eat tadpoles as they would normally. The aim is to stop fish from entering this area to gobble up the tadpoles. Once the tadpoles become adult frogs things become a bit different and they now need to fend for themselves in a whole new way.

You could also use netting to create a division to keep the fish and frog separate within the pond. This isn’t practical for all ponds especially if it’s a large one, but do consider this as an option to keep any tadpoles from being eaten.

Netting can also be used on the surface of the pond to prevent birds from nibbling on the wildlife hiding away during the early weeks of their lives. After these first few weeks have passed survival rates do increase, although the pond owner cannot do anything to prevent predators getting into the water.

Fish do survive on frogs and tadpoles as part of their diet so do not think you can stop this with all the help in the world. Although things like nets do reduce these numbers they will do nothing to stop it completely.

Tadpoles in the wild

However, it is worth knowing that in the wild female frogs will lay up to 3000 eggs. The majority of these grow to tadpoles but will never reach adulthood.

The eggs make a good easy snack for fish and the tadpoles are prey for a variety of tadpoles such as seagulls, dragonfly larvae and. Likewise, gold flies also take on tadpoles which have several other predators including dragonflies, water-boatsmen. The majority of the eggs do not survive to adulthood and will likely end up being eaten whichever predator decides it wants them for its dinner.

Can I move my tadpoles?

When you move tadpoles between ponds it is possible to transfer non-native plants or diseases unknowingly. You can temporarily shift some tadpoles at the same water and take some plants for them to eat and put them back when they have transformed into wild frogs.

You cannot move frogs or frog eggs to a different place you fear it could ruin your Ecosystem. When moving frogs the process requires them to wait until fully grown. This means there is no way to do this until the pond owner knows they do not harm other wildlife. As well as this tadpoles are dependant on insects for food and putting them elsewhere could upset the balance of that pond. It only takes one frog to do some damage, so do not risk your ecosystem by moving things around at all.

Are Tadpoles good for goldfish?

Goldfish eating tadpoles from riparian frogs may be a positive effect on fish. Tortoid tadpoles produce toxic chemicals but goldfish will be cautious about them. Goldfish can eat bread and bloodworms without bread. Find out if your fish can eat worm or food grains or worm foods in order to prevent toxic chemicals found in the tadpole form of tadpole eggs.

Other animals that eat Tadpoles

As already mentioned, yes there are other animals that eat tadpoles too such as birds, turtles and water snakes. These do not have a big impact on frog populations but may introduce diseases. We don’t have to worry about these here in the UK but they do pose a problem in other parts of the world.

We do need to consider the introduction of non-native fish into a pond, as they may eat tadpoles. They do this by consuming them completely and do not leave any evidence behind, unlike a predator that eats a tadpole will usually leave some part of it in the water for other animals to see. This will be enough to deter the predators from eating frogs in future.

Do Koi eat tadpoles and frogs?

Koi do not typically eat tadpoles and frogs, but they do sometimes if they do not have many other options available to them. They do like bloodworms and goldfish do not like the taste of them.

If a frog can fit in a koi’s mouth the frog may eat it. While koi carp were found to eat frogs, it wasn’t a major component as of yet in their diet. If you feed your pet koi fish pellet food this is the major part.

Are fish dangerous to frogs?

The two do not usually get along. The reason for this is that the frog eats the fish eggs and tadpoles. If you add a large number of fish to your pond, it may lead to an increase in tadpole numbers as they do produce quickly, but do not pose a threat since their predators are many.

How do tadpoles survive without being eaten?

Tadpoles do not have any natural predators in their own right, but they do have to grow quickly to fend off the predators that eat them. They rely on natural factors to help them cope with these predators and this includes things like camouflage and poisonous chemicals found in them. This is why you can play your part in protecting them from fish by giving them somewhere to hide away in safety.

Will tadpoles eat small fish?

Tadpoles are omnivores throughout most of their life. They’ll come across many different foods, including vegetation and dead insects but also water striders or small fish to name just a few! As they develop into frogs/toads tadpole diets change again becoming almost exclusively carnivorous.

Do fish eat small frogs?

Yes, if predator fish find some available source of prey while they’re out looking for food then there’s no doubt that a fish big enough to fit the frog into its mouth will take advantage. In winter when food is harder to come by, you can be sure those same cold-blooded creatures won’t hesitate to slurp up any little bugs hiding underneath the surface!

Are frogs bad for fish ponds?

With so many ponds in the wilderness, it’s no wonder that there are frogs and tadpoles. However, there is one type of animal America Bullfrogs pose a danger to small fish, tadpoles and other creatures living around their habitat – sometimes even eating them!


Do fish eat tadpoles – yes they do and the only way that tadpoles will be able to survive without being eaten is by using camouflage or toxic chemicals found within themselves. You may also need to play a part in protecting frog populations by giving them somewhere safe and secure for frogs of all sizes to hide out when predators are around.
