My fish has white spots. Is it ich? What's the best tank 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 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.

Gradually increase the water temp to about 80 F. This will speed up the lifecycle of the parasite. Once all the spots have dropped off the fish, you can use a commercial ich treatment. Look for one in the aquarium section of the local Petco. Follow label directions carefully. If you have just a few fish in the tank, you can remove them to a separate tank after the spots have dropped off. Leave the main tank empty for 4 days at 80 F. The ich parasite cannot survive without fish, so they will die. After 4 days, perform a partial water change, vacuum the substrate, wipe down tank furniture and return the water temp to normal. Acclimate the fish to water temp before returning them to the water.

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.

It is difficult to determine since the image is not clear. Fish are very hard to photograph! If it does, then it is very early infection. Ideally, new fish should be quarantined for at least 2 week sin a separate tank to confirm good health prior to introducing them into the main tank. Monitor for worsening symptoms. If necessary, you can purchase an ich treatment and treat the tank. Look in the Aquarium section of the local Petco. Follow label directions and remove the carbon filter insert during treatment if indicated.

Sounds like ich AKA White spot disease. It is a highly contagious, communicable disease that can and will spread to other fish in the aquarium. If you go to your local aquarium supply shop, they will have several products specifically designed to combat this disease. It will also be recommended to do some changes to your tank environment. You will definitely need to do a water change, over the course of the next 3-5 days. Hope this makes sense.

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.
