Hello! Please help. I was cleaning my betta fish’s tank and I think I accidentally ripped one of his fins. I feel awful. Is there anything I can/should do? Will he be ok?

My Betta Fish Fin Ripped During Tank Cleaning? What to Do

My daughter put three betta females together.. They were fighting to the point where fins were lost.. I took the aggressive betta out.. The injured two are together getting along. What can I do to help them heal?

Maintain pristine water quality. That's the cornerstone for healing and recovery. Use plain aquarium salt (NOT table or Epsom salt) as a general tonic to reduce stress, improve gill function, treat minor infection and aid in recovery. Dissolve 1 teaspoon of salt per gallon of water in a cup or two of tank water and gently pour it into the tank. Treat with salt for no more than 14 days then reassess fin condition. Perform partial water changes afterwards to decrease salinity. Use only conditioned water that is temperature matched to prevent stress or shock. Bettas do best between 78 F and 80 F.

I was wondering if Betta fish fins grow back. I had recently made a mistake when putting two male bettas in a divided tank and one of them has a habit of putting his fins through to the other side (since it had previously housed a baby). The result w

As long as the damage is not too severe, they should regrow. Clean water is critical. Use a water conditioner such as StressCoat to aid healing. Be sure to maintain water temperature between 78 F and 80 F.

Maintain pristine water quality via filtration and regular partial water changes. Use only conditioned water that is temperature matched to prevent stress or shock. Maintain proper temperature as well. Both are important for treatment and recovery. Bettas are tropical fish and do best between 78 F and 80 F. Treat with the aquarium salt (NOT table or Epsom salt) for no more than 14 days in a row. Use no more than 1 teaspoon per gallon of water. Reassess afterward 14 days. If necessary, an antibiotic, antifungal or 'all in one treatment' can be used. Look in the Aquarium section for these products. Follow label directions carefully and remove the carbon filter insert during treatment if indicated.

My betta fish has fin rot, it’s progressing very fast. Within a day there’s a noticeable difference. He’s in a 55 gallon glofish tank(I tried multiple dividers and he kept escaping with no injuries) yesterday I put some betta fix medicine but it took

It may be easier (and more economical) to use a one or two gallon vessel to use as a "hospital tank". Use the water from the main tank initially and change the water in the smaller tank every couple days. For the small amount of water, you can use a water conditioner such as Prime (by SeaChem). Find it in your local Petco. A bit of StressCoat will also aid in recovery. Maintain pristine water quality and proper temp (78F to 80F) to aid in healing. Make sure he continues to eat normally as well.

Hi! My female betta fish has been recently losing bits of her tail. I know the problem is not fin rot because the ends are not black. My betta had this happen to her once before, and once I did a water change it stoped. Why is this happening? What

This is likely fin rot. The tips are not always blackened with rot, they can simply appear ragged. The condition typically resolves by maintaining pristine water quality as you have seen previously. Perform regular partial water changes. Use only conditioned water that is temperature matched to prevent stress or shock. Bettas are tropical fish and do best between 78 F and 80 F. If possible, turn down filter flow to the lowest setting. Bettas prefer slow moving water.

There is an evident hole on my betta's rear fin. Along with that I think it's fins are turning whitish. Is this a major problem?

This is likely a degree of fin rot. The first step in management is by maintaining pristine water quality via filtration and regular partial water changes. Use only conditioned water that is temperature matched to prevent stress or shock. Bettas do best in slow moving water between 78 F and 80 F. If possible turn down the filter flow to the lowest setting or redirect it against the side of the tank. You can use a broad spectrum antibiotic or all-in-one product to treat infection. Look in the aquarium section of the local pet store Follow label directions and remove the carbon filter insert during treatment if indicated..

I got a new betta in January, and I'm starting to notice that his tail is fraying a bit. I'm concerned because I have another betta, and his tail is really frayed too, but I thought that maybe he was always like that. But I definitely know that the n

Check the strength of the current created by the filter. Bettas do best in very slow moving water. A strong current can actually damage long finnage. Be sure to use a conditioner at each water change. My preferences are Prime, NovAqua, AmQuel Plus, StressZyme or StressCoat. You can find these in the aquarium section of the local Petco. You don't need to use all of them though. A bit of plain aquarium salt (NOT table or Epsom salt) can also aid in healing. Dissolve up to 1 teaspoon of salt per gallon of water and treat for 10-14 days then reassess fin condition.

My betta fish has two black patches that resembles eczema on the side of her body and a very small whole on her anal fin. Help

The black patches may be due to elevated ammonia levels. This may cause "burns" on scales. Perform a partial water change immediately. Use only aged or conditioned water that is temperature matched (78 F to 80 F) to prevent further stress or shock. Poor water quality can lead to fin rot or infection. This can be remedied, in most cases, by maintaining water quality. You can add a bit of plain aquarium salt (NOT table salt) to aid healing and reduce stress. One teaspoon of salt per gallon of water is recommended. Dissolve it completely in a cup of tank water then gently pour it into the tank.

Since it is a small tank, you can do 50% or greater water changes every few days or even daily if necessary. Be sure to use only aged or conditioned water that is temperature matched to prevent further stress or shock. Bettas do best between 78 F and 80 F. My personal preference for water conditioners are AmQuel Plus, NovAqua and StressCoat. Mild fin rot can be treated with plain aquarium salt (NOT table salt). Dissolve 1 teaspoon of salt per gallon of water in a cup of tank water and gently pour it into the tank. Perform a 100% water change daily, treating the new water with salt at each change. Treat for 7-10 days, then perform a complete water change without salt.

Can a betta regrow an entire missing fin? I saw a female betta at the store who was in a community tank and her entire left fin was bitten off.

Given the right tank conditions and diet, she may regrow all or part of her fin. Maintain pristine water quality via filtration and regular partial water changes. Offer a healthy diet and minimize stress. It can take weeks to months, so be patient.
