My dolphin's frozen fish has white spots. Are they parasites?

Thanks for reaching out about Dart and including photos. The lesions are not clearly visible in the pictures but by the description, could be parasitic as in salt water ich (cryptocaryon). A veterinary visit could provide diagnostic services, as a skin scrape and recommend a treatment plan. Other fish will be affected so treatment should include the entire aquarium. Good luck.

Thanks for reaching out about Peaches and including photos. One concern would be a parasitic infestation, such as Ich. Contacting Petsmart to see what their recommendations are, would be a first start. A veterinary visit should be scheduled, a skin scrape to identify the parasite and recommend a treatment. If it is Ich, this requires a prolonged treatment over several weeks. Good luck.

Thanks for reaching out about your fish. Dermatitis can be caused by poor water quality, bacterial infections and parasitic infestations. Checking water quality first, is the easiest. Correct any concerns. A skin scrape and microscopic examination is needed to diagnose parasites, as different parasites require different treatments. Antibiotics would be needed to treat a bacterial infection. Seek an examination with an aquatic veterinarian. Good luck.

Sorry for the problems. Intestinal parasitism can affect small fish. Please check water quality to ensure ammonia, pH, nitrates and nitrites are appropriate. Taking a fish to a veterinarian for identification of the parasite can lead to a treatment plan for the adults. Sometimes invertebrates (snails) are intermediate host for the parasites, and removing them can reduce the problem. Good luck.

The tiny spots could be a parasite infection. Ich presents as small dots similar to grains of salt. It will quickly overrun a tank and can kill fish if left untreated. You will need to treat the entire tank as opposed to just affected fish. A broad spectrum parasite medication that covers ich can be purchased at the local Petco. Follow label directions carefully and remove the carbon filter insert during treatment if indicated.

Thanks for reaching out about your aquarium and including photos. Did you test your water quality prior to the water change? Continue to test for pH, ammonia, nitrites and nitrates. Pristine water quality is needed for health. Are any of the fish new, that could have introduced parasites? Itching/flashing can be due to water quality, external parasites, bacterial or viral infections and other causes. The white lesions on the photo could be fungal infections. A skin scrape and examination under the microscope (at a veterinarian's office) is needed for an attempt to determine a cause. Fungal infections are often secondary problems, so check water quality first. Good luck.

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.
