Possible Reasons Why Your Betta Fins Are Shredded
The most common cause of betta fish shredding their fins overnight is sporadic swimming. There are other possible reasons, but if it happened overnight, it can be the leading cause.
Before getting into other reasons, you have to understand how easily your betta fish fins might get damaged. First off, betta fish are very curious creatures, that like to explore their aquariums, and sometimes fit in some places that they should not be. At the same time, betta fish are predatorial fish, which means they like to hunt and move a lot. Thirdly, long-tailed betta fish don’t have a very strong immune system, since they have been heavily inbred.
In nature, betta fish have very short fins, and these long-finned betta fish have been bred for the purpose of money. A lot of long-tailed betta fish have a hard time swimming around, and can easily damage their fins in multiple ways.
Sporadic Swimming
The first way that your betta fish might get their fins shredded overnight is by swimming sporadically. It might look like betta fish are slow and calm sometimes, but they can swim and jump very fast. Betta fish can rip their fins swimming very fast, similar to how humans pull a muscle while running.
When this happens, betta fish usually have just a few rips in their fins, and the damage should heal on its own in time. If the damage on your betta fish tail does not go away or becomes even worse, sporadic swimming is probably not the cause of your betta fish injury.
Fin Rot
The most common reason why betta fish fins are shredded is fin rot, but this does not happen overnight. Fin rot mainly occurs because of bad water quality, and stress. High ammonia levels or improper water conditions (temperature, pH) can lead to your betta fish becoming weaker and developing fin rot. This disease can lead to more severe betta fish diseases like dropsy and ulcers. so you can’t leave it untreated.
This is a bacterial infection, that slowly destroys your betta fish tail and fins, and can lead to death. The easiest way to tell fin rot apart from other injuries is the appearance of the betta fish fins. If your betta fins are ripped apart and have black or red edges at the very end, it can definitely be fin rot. Don’t worry, because betta fish fin rot treatment is not that hard, and usually, these fish make a full recovery.
Betta Fish Tail Bitting
Moving on, another common betta fish fin shredding cause is that some betta fish bite their own fins. Betta fish can easily damage its own fins or tail overnight. It might look surprising to you, but this is a very common problem when keeping long-finned betta fish. These creatures can bite their own tails for various reasons. The first one is boredom. If your betta fish lives in a very basic setup and does not have anything to interact with (tank mates, plants, other decorations), it can start biting itself.
The second reason betta fish bite their fins is reflection. Some bettas attack their own reflection because they think it is another betta fish. This can also trigger tail biting. Consider adding more plants or painting your aquarium glass to reduce reflection.
The third reason is stress. Betta fish can be highly territorial creatures and can get very stressed seeing other fish or aquatic creatures. Even the most basic aquarium tank mates like snails or shrimp can stress out some betta fish, which can result in tail biting. Remember, that every betta fish is different, and not all of them can have tank mates.
Fin Nipping Tank Mates
A very common issue with betta fish is that smaller and faster fish can fin-nip your betta. This can also happen overnight, and you should monitor the behavior of your betta fish tank mates, to make sure that this is the cause of your betta injury.
Although it is not always the case, some tetra, rasbora, and barb species can be very aggressive fin nippers. Fin nipping is very situational, and does not occur every single time with the same species. This problem actually has a deeper meaning: if your tank mates are fin-nipping your betta, they probably feel stressed, or there is not enough room for all the fish.
This problem can be solved in a couple of ways. Firstly, try to rearrange your aquarium, so that your betta fish tank mates would have something else to focus on. If that does not work, I highly suggest rehoming your betta fish, or the fin nippers, that are causing you problems. If the fin-nipping is stopped, your betta will heal on its own.

Sharp Decorations
Moving on, some plastic or ceramic decorations can easily shred your betta fins overnight. Betta fish are known for being clumsy sometimes, so it is possible, that they ripped their fins on something sharp. This problem is easily solvable since you can just remove the sharp object from your aquarium. Your betta fish fins should heal in no time.
Aquarium Filter Water Intake
The last cause of shredded betta fins is the filter. In some filters, the water intake part can easily suck your betta fish fins, causing injury. Although this is very rare, it has happened before in the hobby for a bunch of fish keepers. Also, if your filter creates a very strong current, it can also injure your betta fish, when it accidentally swims in that current without knowing.
If that is the case, try to cover the water intake part, so that it still works, but the betta fish can’t get near it, and at the same time reduce the water flow level. This should prevent any more scenarios, where your betta fish might get injured again.
How to Treat Ripped Betta Fish Fins?
There are a couple of different things you can do to treat your betta fish and it’s ripped fins. If you successfully diagnosed the root cause of the injury in your betta fish, now is the time to take action.
Clean Your Betta Tank
A clean environment is key when keeping fragile fish like bettas. Make sure that you do not have a significant amount of excess waste built up in your aquarium. Do regular water changes and test your water for harmful toxins like ammonia, nitrites, or nitrates.
If your betta fish does not have significant damage to its tail, a clean fish tank will be enough for it to recover to its original beauty. Be sure to stay consistent with maintenance, because the well-being of your betta fish depends on it.
Add Salt to Your Betta Fish Tank
If the damage to betta fish fins is worrying, you can use aquarium salt in your tank. Aquarium salt is commonly used to treat various betta fish fin diseases, and in most cases, it helps even the most beaten-up bettas recover fully.
Salt is also very beneficial to betta fish, as it provides lots of positive factors to the health of these species. It significantly speeds up the process of wound healing, helps the slime coat of the fish regenerate faster, and gives some breathing room for the betta fish’s immune system to recover.
Consult a Fish Veterinarian
If you don’t see any progress in your betta’s wound healing, be sure to consult a professional in this matter. Fish veterinarians can prescribe other possible medicine for a ripped betta fish tail, like antibiotics.
