My betta fish has a skin gap from injury. Will it heal and grow back?

As long as you maintain pristine water quality via filtration and regular partial water changes, he should heal up. Use only conditioned water that is temperature matched to prevent stress or shock. Bettas do best between 78 F and 80 F. Consider a product, such as Stress Coat, to promote healing. https://www.petco.com/shop/en/petcostore/product/api-stress-coat-aquarium-water-conditioner

Thanks for reaching out about Kai and including photos. It is difficult to determine is this is a full-thickness hole by the pictures. Tails tend to regenerate so monitor to make sure it doesn't get worse. Test and correct any water quality concerns. If other spots occur, testing for parasites by a veterinarian is recommended. Good luck.

Thanks for reaching out about Gummy. Not sure of biting the tail is normal, especially if chewing to the point of removing part of the tail. Itching or irritation are most likely. Test and correct water quality including pH, ammonia, nitrite and nitrates. These can be dermal irritants. Bacterial or parasitic concerns, spinal problems (scoliosis due to vitamin C deficiency) are also common and a veterinary visit would be needed to assess and provide a diagnostic/treatment plan. Good luck.

Hello, Sometimes fish can lose scales from minor trauma, in which case it may be fine. However, if Mr. Nugget lost his scale from an infectious disease or internal health problem, this could be the beginning of illness. I'd recommend checking his water parameters and ensuring his environment is ideal as the first step for any sick fish. I hope this is helpful. Thanks for using Petco Pet Education Center, formerly Petcoach.

Consider placing him in a hospital tank. Maintain pristine water quality. That's the foundation for healing. Perform partial water changes every few days if necessary. Use only aged or conditioned water that is temperature matched to prevent stress or shock. Add StressCoat or similar product to promote a slime coat. Plain aquarium salt (NOT table or Epsom salt) can be used to reduce stress, improve gill function, treat minor infection and aid in recovery. Dissolve 1 tablespoon of salt per 5 gallons of water in a cup or two of tank water and gently pour it into the tank. Treat for 10-14 days then reassess his condition. It will take time for him to heal. He may not fully heal, but it he can eat and swim, he should be fine.

Even though a picture of it would help to determine the nature of this wound more specifically and give you specific advices on how to give appropriate treatment. Generally speaking you can follow these guidelines: - set up quarantine tank: make sure the tank is well oxygenation and has some plants for hiding; - add 1 teaspoon of aquarium salt per gallon; - add this product https://www.liveaquaria.com/product/4410/?pcatid=4410 as indicated; - leave your fish there and feed him regularly for 3-4 days until you don't see any improvement - If no results at all are seen after 4 days a check up would be needed. Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further. Please find the time to give us a feedback about the consultation as that will be used to improve our service.

Thanks for reaching out about Kai and including photos. This could be a solitary Ich lesion (which is unusual, as there are usually multiple) or a hyper-active mucous gland. Check water parameters for pH, ammonia, nitrites and nitrates, correcting any problems. If more lesions appear, a veterinary visit can help with a diagnosis through a microscopic examination of a skin scrape, and therefore prescribe the appropriate treatment. Good luck.
