Will Guppy Fins Grow Back? Here Are The Facts


Guppies are some of the most common fish to take care of because they are relatively easier to keep compared to other aquatic creatures. But while Guppies may be easy to take care of, there will be times when you would notice that one of your fish will have nips and tears in its tail fins for one reason or another. Is this a cause of concern for you? Will Guppy fins grow back?

Most types of fish will grow their fin tails back. This includes Guppies. However, there are a lot of factors that will contribute to whether or not your Guppy will grow its fins back. But as long as your Guppy is in a clean environment and that it is healthy enough, you probably don’t have to worry a lot.

Guppies, like most fish, do indeed have amazing regenerative abilities but it still depends on how well you take care of them and on the type of environment you provide to your pets. As such, you should know more about how to properly take care of your Guppies if you want to make sure that they get to regenerate really well.

Can Guppy Grow Fins Back?

One of the things you need to understand when you are taking care of fish is that it is quite normal for them to encounter injuries that include nips and tears on their fins. That’s because, like any other animal, injuries are normally encountered by fish especially when they are living together with other fish, and if there are some obstructions in their habitat that can lead to injuries. Of course, Guppies encounter injuries to their fins as well.

If you are taking care of Guppies, by now you must know that they have amazing appetites to the point that they will eat practically anything. Yes, this includes other fish and Guppies, as well as smaller Guppies, who will most likely get bullied or even eaten by bigger adult Guppies.

And if you are keeping other types of fish, it can also be normal for the bigger ones to bully your Guppies by biting off and nipping off some of its fins for one reason or another such as their natural territorial tendencies or maybe because they were hungry and they were just exercising their predatory nature of trying to hunt down smaller fish.

Because of all of those factors, your Guppy can actually encounter injuries to its fins to the point that it will be missing some tail fins. If you must know, tail fins are necessary to a Guppy or to another fish because this is what allows them to swim and move around the water effectively similar to how we use our legs to walk properly. So, if a Guppy has an injured fin, it will most likely find it more difficult to swim just as mammals would find it more difficult to move on land when they have injured legs.

But, just like how we can heal from our injuries, can Guppies eventually grow their fins back as well? Yes, Guppies have the regenerative abilities that will allow them to grow their fins back. Simple injuries such as small nips and torn fins can be grown back by your Guppy. And you will be surprised by how your Guppy will still retain the same bright color it had in its fins when it grows it back so long as the injury was not too serious to the point that it will become difficult for it to grow the tail fin again.

Meanwhile, if your Guppy has an injured fin that is not just a simple tear but has become a bit more serious, it may still be able to grow the fin back depending on how healthy and young it is. The healthier and younger the Guppy is, the more likely it will be able to grow its fin back either with the same color as it was before or in a transparent color.

However, the more serious the Guppy’s tail fin injury has become, the less likely it will grow back. That said, if your Guppy has a very serious tail fin injury where you will already see some flesh and blood coming out of it, there will be little to no chance that it will end up growing back similar to how we cannot heal an injury where too much flesh has already been torn out. In that sense, your Guppy may end up dying soon because of the injury it suffered as it will end up getting infected or perhaps bleed to death.

But, as long as there is nothing that will injure your Guppy to the point that the tail fin injury has become too serious, any tear or nip in its fin can grow back. Still, though, you have to make sure that there are no other predatory or territorial fish that will end up bullying or even eating your Guppies so that you can minimize the chances of them suffering injuries that are too serious for them to regenerate and come back healthy from.

How Long Does It Take For Guppy Fins To Grow Back?

So, if a Guppy can regenerate from a minor to moderate tail fin injury, how long does it usually take for it to recover and grow its fin back? Well, it really depends on how serious the tail fin injury is as more serious injuries will naturally take longer to heal in comparison to the less serious ones.

If the Guppy is healthy, eating well, and that is still at the prime of its lifespan, it will take only a few days for it to heal a minor injury such as a small nip or a tear in its tail fin. Give it about two to four days and you will see its fin back to what it was and with the same bright color that it had prior to when it was torn off. However, tail fin injuries that are more serious might take a while to recover but you can give it at least five days and you might see it healing.

On the other hand, a Guppy that is older and less healthy might take more time to heal an injury such as a torn tail fin. It might take at least four days for it to heal a minor nip or tear and will take maybe at least a week for it to recover and regenerate a more serious injury. And there will be no guarantees that it will be back to the way it was prior to when it injured its tail fin.

What Happens When Your Fish Lose Their Tail Fins?

At this point, you might be wondering what will happen if a fish loses its tail fins? The tail fins are there for a purpose similar to how our legs have a purpose. It really is the same way when it comes to fish.

If you happen to have tried scuba diving, you would know that you need diving flippers to move well underwater against the strong current of the water. In the same way, fish would need their tail fins to effectively move underwater as that is what helps them navigate through the currents. A fish with a tail fin injury would find it difficult to swim.

However, if your Guppy is missing just a small piece of its tail fin, it will still be able to swim finely but you should expect that it might not be as quick and as lively as it once was. Meanwhile, the more serious the injury is, the more difficult it will be for your Guppy to swim. And if a Guppy can’t swim, it will end up suffering health-wise or may eventually die.

The first thing you can do is to continue to monitor its environment. Make sure that it is swimming in clean water and that there are no obstructions that will make it more difficult for it to move around. Notice how the other fish around it react as well as bigger fish might sense the weakness in the Guppy and may end up bullying it.

One other thing you can do is to make sure that you feed the Guppy well enough for it to recover so that its health won’t be affected. See to it that you are providing enough nutrients such as fat and protein so that it can recover well enough and grow back its tail fins. Always remember that a healthier Guppy will have an easier time recovering from a tail fin injury.
