My fish has an open wound. What's the best way to treat it at home?

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; unfortunately it is very difficult to replicate the composition of aquarium salt back home so I would strongly suggest to buy a specific product. - 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 as more specific tests may be needed to establish a specific diagnosis. 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.

It needs to be separated into a hospital tank by itself so it can be treated and heal. If you leave it in the main tank, the others will continue to pick and nip until it dies. Maintain pristine water quality and chemistry during treatment. You can use a broad spectrum antibiotic for 10-14 days to treat infection. You can find one, such as Maracyn 1 or 2, Kanaplex or Furan, in the aquarium section of the local Petco. Follow label directions carefully and remove the carbon filter insert during treatment if indicated.

Maintain pristine water quality and stable chemistry. If the fish is not a scaleless fish, you can use plain aquarium salt as a general tonic. It will reduce stress, increase gill function, treat minor infection and aid in recovery. Dissolve 1 tablespoon of plain aquarium salt (NOT table or Epsom 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 the condition of the injured fish. Partial water changes can be performed afterwards to reduce salinity. Use only aged or conditioned water that is temperature matched to prevent stress or shock.

Thanks for reaching out about Candoris and including photos. A veterinary visit is recommended as systemic antibiotics needed. Medications added to the water are not absorbed systemically and will not help with internal infections and will likely affect the biological filter. Check and correct water quality as pristine conditions needed to heal. Adding 1 gram non-iodized salt (aquariums salt) per 1 Liter, to decrease stress and osmotic load on the fish. Good luck.

Separate him into a smaller quarantine tank. You can use a broad spectrum antibiotic to treat him. Read package directions carefully and remove the carbon insert if necessary during g treatment. Plain aquarium salt (NOT table salt) can be used concurrently to aid healing. Dissolve 1 teaspoon per gallon of water into the tank. The Ich can be managed by gradually to about 86 F. Raise it no more than 1 degree per hour to prevent stress. This will speed up the life cycle of the parasite. Once the "dots" drop off your fish, you can vacuum the gravel daily and sanitize any tank furniture. Keep the temperature elevated for about two weeks to ensure resolution. Reduce the temp gradually after this time period. A medication such as API's QuickCure can also be used in conjunction with a temperature increase.

Thanks for reaching out about your Oscar and including photos, but difficult to see the HLLE lesions due to too dark. The eye looks terrible and systemic antibiotics are recommended at the least. A veterinary visit is highly recommended to clean the wound and provide other possible treatments. The water quality must be kept pristine (pH, ammonia, nitrites, nitrates) to assist recovery. Antibiotics added to the water do not penetrate into the body, nor do fresh water fish drink, since osmotically water enters over mucous membranes (gills, mouth, skin) and antibiotics do not cross this barrier. HLLE causes can be multi-factorial including water quality, bacteria, parasites, carbon particles in activated charcoal (filters), low vitamin C, etc. Check and correct water quality, replace existing food if older than two months (vitamin C degrades quickly), see a veterinarian with fish experience. Good luck.

It could be early ich (white spot) infection or another infection (bacterial or fungal). To be safe, separate him into a quarantine tank and monitor for any change. You can treat for ich as you did it in the past if indicated. Bacterial and fungal infections have different treatments, so I would be hesitant to recommend a specific medication without more information or a definitive diagnosis. You can use plain aquarium salt (NOT table salt or Epsom salt). As a general tonic to reduce stress, increase gill function, treat minor infection of many types and to aid in recovery. This can be added to the quarantine tank at 1 teaspoon per gallon of water. Treat for 10-14 days then reassess the condition.
