Thanks for reaching out about Fish. Test and correct water quality for pH, ammonia, nitrites and nitrates. If all fish are affected, water quality problems the most likely. Alteration can lead to increased mucous production from the skin (white stuff), but fungal dermatitis or parasites are also possible. A veterinary visit is recommended if the water quality if appropriate, to assess and provide a diagnostic/treatment plan. Good luck.

Thanks for reaching out about your axolotl. Fungal spore are ubiquitous in the environment but a UV sterilizer can help. There are anti-fungal treatments to add to the water or dip treatments that could also help. A veterinary visit is recommended to assess and provide a diagnostic/treatment plan. Fungal infections are usually secondary problems, so review environmental parameters such as water temperatures, pH, ammonia, nitrates and nitrites. Review diet to ensure well rounded nutrients. If wanted, you can arrange for a private consultation. Good luck.

Without an image, it is difficult to make detailed recommendations. In general, maintain pristine water quality and chemistry. Monitor for elevated ammonia or nitrite levels and perform partial water changes as needed. Use only conditioned water that is temperature matched to prevent stress or shock. Consider adding in a second antibiotic, such as Kanamycin, to treat gram negative bacterial infection. When treating the tank, be sure to remove the carbon filter insert during treatment.

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.

Thanks for reaching out about Gerald. First, test and correct water quality for pH, ammonia, nitrites and nitrates, as first need healthy conditions to prosper. A veterinary visit can assist with a skin scrape and microscopic examination in an attempt to conclude a diagnosis and prescribe a treatment. Infections, parasites, water quality and dietary deficiencies are just a few of the potential problems. Antibiotics in the water do not penetrate deep and do not treat internal infections, this would require oral or injectable medications. Good luck.
