I would recommend to call the local pet stores (including Petco) and ask if they ever carry that species. Sometimes the fish can be out of stock. Some of the smaller fish stores can have a good variety of fish available. Best of luck!

The Cowfish, or Longhorned Boxfish, is a marine species that should be kept only by experienced aquarists. When stressed, they can release toxins into the water which may harm tank mates. Pacman frogs, leopard geckos, corn snakes or bearded dragons are all easy to keep.

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!

Most puffers will not eat flakes or pellets. They need live or frozen foods. They also require hard foods to keep their teeth worn down. The local Petco will likely have these foods in stock. If the tank is overstocked, he may be stressed. He may also have an infection (bacterial, fungal or parasites) that are causing his symptoms. Ideally, a new fish should be quarantined for 2-4 weeks before being introduced to the main tank.

Thanks for reaching out about you fish. It is believed to be a Comet goldfish. Water quality and nutrition is the key to success. Testing water parameter for pH, ammonia, nitrite and nitrate will give you guidance for a healthy environment. Purchased food should be rotated out every 3 months as vitamin C and other nutrients degrade over time. Trying to maintain water temperature can be challenging with out a heater, but most fresh water fish tolerate some changes. Good luck.
