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!

Thanks for using Boop by Petco! This could be due to pain or discomfort as he could have hurt himself. However, it could also be coincidental. If he is otherwise doing well without limping, I think it would be ok to monitor him for now. However, if he develops a limp or any other signs such as crying in pain, inappetence or continued lethargy, have him evaluated by a veterinarian for further assessment and treatment. They can check him for any evidence of pain and treat him based on findings. Good luck and have a great day!

Without anything to use for scale, it is hard for me to tell how big your tank is, but in general it seems very small. Also, the water that is in the tank appears very cloudy right now, so that would be the first place to start. Water quality is very important, and will make or break your ability to house and care for fish. I would recommend getting a good filter system (you can visit a local pet store to assist you with brands in your area, as I am not familiar with what you can get in India). Be sure to bring the measurements (height, length, width) of your tank, or the gallons or liters so they can tell you what capacity of filter you will need. Everything else will depend on what types of fish you get - if you plan on getting multiple fish, they will need to be small - a general rule of thumb is one square inch of fish per gallon of water. Depending on the species you get, you may need to also get a bubbler to ensure there is enough oxygen in the water for them, and you will also

Customers under the age of 18 cannot purchase live Companion Animals or Aquatic Life without a parent or guardian present. (Excluding crickets and worms). Due to the demands of time and intricate care required with certain species, it is in the best interest of the animals to not sell to minors. Parental permission at time of sale will ensure a better home for the animal and lower our rate of return.

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.
