Why are my fish dying with grey spots? How do I treat their illness?
Check the water chemistry. The discoloration could be due to elevated ammonia levels which can cause "burns". Use a home test kit or submit a water sample for testing. The local Petco may do this for free or for a small fee. Aim for an absence (0 ppm) of ammonia and nitrites with nitrates at 20ppm or less. Perform partial water changes to stabilize chemistry and/or to improve water quality. Use only conditioned water that is temperature matched to prevent stress or shock. The Neons (blue fish) appear to be infected with Ich, a parasite. Treatment is possible with commercial products found in the local Petco. Follow label directions carefully. You will need to treat the entire tank until all traces are gone. Removing a lump from your fish on your own is never recommended. You can cause severe injury. Most broad spectrum antibiotics (Kanaplex, Maracyn, Maracyn 2, etc.) found in the aquarium section of the local Petco should help treat or prevent infection. Choose one and follow label directions. Remove the carbon filter insert during treatment if indicated. Maintain pristine water quality via filtration and regular partial water changes to aid in recovery. You can feed frozen worms, just thaw then first in a small cup then place them in the tank.

My Arowana only eats live fish. What should I feed it instead?
Thanks for reaching out about Arrow. Dried shrimp is an inappropriate diet for fish as low in calcium (no bones), high in phosphorus. Being dried, many other nutrients (vitamins) are destroyed. A commercial pellet in addition to whole fish is recommended. Monitor water quality as healthy water is important for a healthy fish. Good luck.

My fish have growths, tattered fins, and are flashing. What's wrong?
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.

How to safely feed fish parts to dogs, especially with cancer?
Hello. You can definitely feed the fish parts, but make sure they are thoroughly cooked to prevent the transfer of parasites or bacteria to your dogs. After cooking ( whatever method you prefer ), you can feed all parts if they are rather soft. Any sharp bones, scales or body part to tough for you to chew should either be discarded or ground up. High levels of omega fatty acids from fish are always a great supplement to any diet, especially a cancer diet. Thanks for using Petco Pet Education Center, formerly Petcoach.
