Waking up to find your betta’s fin damaged or missing is a scary sight. Luckily, betta fins can regrow.
However, it’s crucial to identify the cause of your betta’s fin loss to promote regrowth and prevent fin destruction from happening again.
How Long Does It Take Betta Fins to Regrow?
If your betta’s fin is completely gone, you can expect it to take up to a few months to regrow.
However, if only a portion of its fin has damage, it’ll likely take much less time; within a few weeks, it could look new again.
That said, betta fin regrowth usually isn’t a linear process.
Your betta fish will be off-balance from losing its fin and will likely bump against the side of the tank and into other objects.
To gauge just how long it may take for your betta’s fin to grow back, you can compare it to your fingernail growth, as its fins regrow at approximately the same rate.
Signs of Fin Regrowth in Betta
At first, it’ll be hard to know if your betta fish’s fins are regrowing. So, you’ll need to examine it closely. Using a magnifying glass could help you during the early stages of regrowth.
You’ll want to look for a transparent membrane growing from the betta’s body where its former fin had been. The practically microscopic membrane will resemble clear plastic.
Naturally, as your betta’s fin regrows, it’ll be easier to spot. Color will eventually appear on the fin, although it might be a different shade than the old one.
Causes of Betta Fin Loss
Knowing that your betta’s fin can regrow is only half the battle.
The other half is getting to the root of the fin loss cause and preventing it from happening again.
Below are some common reasons that bettas lose their fins.
Biting Its Tail
Yes, some betta fish create self-injuries. The reason that betta fish bite their tail can vary, but it’s often a sign that your fish is unhappy.
It may bite its tail because it’s stressed, bored, or has a lot of aggression and needs to take it out on something.
If you went to bed and your betta fish had its tail but then you wake up in the morning to find a lot of it gone, tail biting could very well be the issue.
Some people even think such tail biting has its roots in genetics.
You may enjoy looking at a fish tank packed with vegetation and hiding spots, but your betta’s fins may not feel the same.
Cheap fish tank decorations may scratch or tear at your betta’s fins. Your fish’s flowy, beautiful tail is especially susceptible to damage as your fish swims by various décor.
We’ll talk about what you can do to balance a habitable environment for your betta while keeping it fin-friendly.
As it turns out, your betta may not be the only fish in your tank interested in nibbling on its tail—its companions may target it too.
Larger fish may attack your betta, so it’s critical you keep a close eye on your tank, especially when introducing new fish. In fact, smaller fish may also try to nip at the fins.
Bettas aren’t the fastest breed of fish around. So, it’s difficult for them to escape if one of their tank companions starts pestering them.
While fin rot begins in the fins, it will eventually eat away the fins and continue to work its way inside your betta’s body.
Signs of fin rot include:
- White edge on the fins
- Painful looking fins
- Fin discoloration
If you suspect that your betta has fin rot, the first step is to change its water immediately.
You’ll also need to purchase an antibiotic. Within days, you should start seeing your fish improve.
How to Help Your Betta Recover From Fin Loss
As pet owners, we want to do everything in our power to prevent our fish from suffering.
Provided that your fish’s fin loss isn’t the result of fin rot, which will need antibiotic treatment, a few changes to your tank and care practices can help your betta overcome their predicament.
Below are some best practices for helping your betta’s fin heal. Even after your betta recovers, you should keep up with these strategies to prevent the issue from occurring again.
Maintain Excellent Water Quality
Infections can run rampant in water, which is why you should change it frequently. A good habit to get into is changing approximately ten percent of the water every day.
You also want to ensure that your water doesn’t have a high ammonia concentration. That can be a particularly important item to check for if you use well water.
Ammonia is lethal to betta fish because it poisons their immune system over time.
Give Your Betta Space
Pet stores are misleading because they often sell betta fish in tiny containers. However, this is not how betta fish live in the wild, making it detrimental to their physical and mental wellbeing.
You should offer your betta fish a minimum of a five-gallon tank. A filter, heater, and smooth surfaces they can hide beneath are also essential to a proper betta tank.
Making sure your betta has adequate space will help boost your fish’s mood. By doing so, it’ll have a stronger immune system and will therefore build more resistance to getting fin rot.
Supplement with Daphnia
Daphnia is a tiny planktonic crustacean, which people commonly call water fleas. They compose a large part of a betta’s diet in the wild.
As a result, some people swear by using daphnia as a way to regrow betta fins. As a vitamin B-rich food, it may promote faster fin regrowth.
Either way, adding daphnia to your betta’s diet is an excellent choice. At the very least, it’ll make your betta happy and looking forward to mealtime!
You’ve likely heard that saltwater has healing properties, and this is the case for bettas too. Salt helps your betta produce a greater concentration of slime coat.
Such a coat is critical for preventing bacterial, fungus, and parasites from making a betta’s damaged fin worse.
However, before you run to your kitchen, know that table salt isn’t the right option. Instead, you should purchase salt made for aquariums, which you can buy from your local pet store.
Utilize API Stress Coat
While you’re at the pet store picking up salt, you might as well add API stress coat to your list.
API serves as a water conditioner. It’ll help keep the water in your aquarium healthy and has stress-relieving properties.
Therefore, it helps reduce the likelihood of your betta biting its tail.
Preventing Betta Fin Loss
Fin loss is difficult on your betta, so once it recovers, you’re likely motivated to make sure it doesn’t happen again.
Below are some top tips for ensuring your betta lives a happy life with full, healthy fins.
Choose Décor Wisely
It’s okay to add decorations and live plants to your betta fish tank. In fact, you should do this to keep your betta occupied and replicate its natural environment.
However, it would be best to vet any objects before placing them in the tank to ensure they don’t contain sharp edges or have rough material.
Decorations with smooth edges and live plants are ideal for maintaining betta fin health.
Be Cautious When Adding New Fish
We understand the excitement of having a tank full of colorful fish, but you need to make your betta’s fin health a priority.
Talk with your local pet store to learn about the typical behaviors of different fish species. By identifying more peaceful species, you’ll avoid a potential fin disaster.
Of course, it’s critical to consider the new fish’s fin health as well. Betta fish tend to have an aggressive side, especially towards their own species.
Change Up Their Environment
Happy bettas have a higher chance of having healthier fins.
According to a paper in Animal Cognition, scientists believe that a fish’s perception and cognition are the same or better than many vertebrate animals.
Therefore, some people’s claims that betta fish can hear and recognize their owners might be valid.
Either way, betta fish are intelligent enough to get bored. So, make sure to add and remove different plants and smooth objects in their tank, so they stay entertained.
Help Is On Its Way
We understand how unsettling it is to discover that your betta lost some or all of its fins. However, the important thing to remember is that betta fins can regrow.
Betta owners can sometimes inadvertently cause their fish to lose its fins.
If you identified yourself as one of these people after reading this, don’t beat yourself up for it—every pet owner makes mistakes.
However, we hope the information here helps you cure and prevent your betta from experiencing fin loss in the future.
