Why is my fish not eating, has yellow poop, and a growth under eye?
Check the water temperature. Low temps can affect appetite and digestion in fish. Angels do best between 78 F and 80 F. You can soak food in garlic juice to stimulate his appetite. Next, check the water chemistry. This can be done using a home test kit or by submitting a water sample for testing. Most pet stores will do this for free or for a small fee. Confirm 0 ppm ammonia and nitrites with nitrates at 40ppm or less in a tank with live plants or 20 ppm or less in an unplanted tank. Partial water changes can be done, if indicated, to stabilize chemistry and/or maintain water quality. use only aged or conditioned water that is temperature matched to prevent stress or shock. Although they do best in slightly acidic and soft water, they are quite adaptable. Fast him for 2-3 days then feed bits of cooked and shelled green peas. if he is constipated then this should him him get regular again. A broad spectrum parasite medication, such as PraziPro, should be considered. You can find it in the aquarium section of the local Petco. Follow label directions carefully.

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.

My goldfish has Popeye. What medicine should I use to treat it?
Popeye is a symptom of an underlying disorder in the tank. It can be a result of trauma or infection. Most cases can be managed by maintaining water quality and a broad spectrum antibiotic. Quarantining as you have done is always a good move. Check the tank for any furniture/décor that may cause injury. Check the water chemistry, filtration and temperature next. Any imbalances can predispose a fish to illness. Partial water changes can be done to improve quality and correct imbalances. Use only aged or conditioned water that is temperature matched to prevent further stress or shock. Maracyn Plus or Kanaplex can be found in the aquarium section of the local Petco or fish store. You can use either, in addition to plain aquarium salt (NOT table salt), to treat. Dissolve 1 teaspoon of salt per gallon of water in a cup of tank water and gently pour it into the tank. Treat for 10-14 days with salt then perform partial water changes to decrease salinity. Treat only the amount of water going back into the tank with salt to avoid overdosing.

My fish have white fuzz, aren't eating, and are lying down. What's up?
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.
