Vet Q & A
What's wrong with my fish? White spots, raised scales, swimming low.
Thank you for using Petco Pet Education Center, formerly Petcoach! 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!

My new discus fish has white spots but is acting normal. Is it ich?
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.

My red blood parrot fish has red spots for 2 weeks. What's wrong?
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.

Vet Q & A
Is my orange fish a goldfish or molly, and what's this egg-like thing?
Mollies do come in gold or orange colorations, but it is difficult to determine from that angle. If you can repost a broadside picture in a new question, that may make identification easier. If it is an egg laying species of fish, the third image could be an egg but I have reservations saying definitively without something for scale. It looks too large to be an egg. As an aside, if you leave the Molly fry in with adults, they will likely be eaten. You can separate the out, remove the adults, use a breeder screen or provide plenty of cover for them.

Vet Q & A
My fish's fins are drooping. What's wrong and how do I fix it?
Begin by submitting a water sample for quality testing. Most pet stores will do this for free or a nominal fee. High ammonia levels, PH imbalances may be responsible for that. Oxygen concentration and quality of the filters should be determined as well. If water quality is good and there are no major imbalances, Cosmo should examined to look for any sign of bacterial/fungal infection and eventually water should be treated. Please do not hesitate to contact us again on the forum or by requesting a consultation (where you can post pictures ) if you have any more questions or to discuss it any further.
