Thank you for using Boop by Petco! Ariel does look like she has a little bit of white on her abdomen, and potentially some raised scales. She also appears to be swimming towards the bottom of the tank, but this may just be a coincidence in the photo. The white on the abdomen can be caused by a fungal or parasitic infection, so I recommend separating this fish from the others. You may want to change the water and sanitize the tank if any other fish start to get similar symptoms. I hope this helps and am happy to answer any other questions you may have!

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.

Check the water chemistry. Confirm ammonia and nitrite levels are 0.25ppm or less and nitrates are 40ppm or less. Use a liquid test kit or submit a sample for testing. Most pet stores or aquarists will do this for free or for a small fee. Partial water changes, about 30% can be done to decrease high levels. Use only aged or conditioned water that is temperature matched to prevent further stress or shock. My preferences for water conditioning are AmQuel Plus and NovAqua in addition to StressCoat. Confirm water temperature between 78F and 80F. You can soak pellets in some garlic juice to stimulate his appetite.

Anytime there is an unexpected loss of fish, water chemistry should be checked. Use a home test kit ( https://www.petco.com/shop/en/petcostore/product/api-freshwater-master-test-kit# ) or submit a water sample for testing. Most pet stores will do this for free or for a small fee. Confirm an absence ( 0 ppm ) of ammonia and nitrites with a nitrate level of 20 ppm. pH can range between 6.5 and 8, water temp should be 65 F to 75 F. If chemistry and water quality are within normal parameters, then illness or aggression would be other reasons for the loss. It is always recommended to quarantine fish in a separate tank for 2-4 weeks prior to adding them to the main tank. During this time, they can be treating for infection or parasites. I am sorry for the loss of your fish.

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.
