Does Petco sell Mr. Ros marine phytoplankton EPA for dogs and cats?

The experts here on the forum at Boop by Petco do not work at Petco stores and I don't think anyone would have knowledge of inventory at local stores. I cannot find this particular product on the Petco website. It's possible that it's available at your local store and you could try giving them a call. There are a number of other fatty acid supplements listed on the Petco website that may or may not be available in your local store: https://www.petco.com/shop/SearchDisplay?searchTermScope=&searchType=12&filterTerm=&maxPrice=&top_category=&showResultsPage=true&langId=-1&beginIndex=0&advancedSearch=&sType=SimpleSearch&metaData=%5BLjava.lang.String%3B%4065f965f9&pageSize=24&manufacturer=&resultCatEntryType=2&catalogId=10051&pageView=grid&searchTerm=fatty+acid&minPrice=&urlLangId=-1&categoryId=10056&storeId=10151

Best tropical fish for a 20-gallon tank? Can I donate fish to Petco?

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!

Is a 1-foot marine tank big enough for fish? What can I put in it?

It is very difficult to get a good biotope in a just 1 foot long tank unless it is a few feet high. You will not be able to keep fish in it, only invertebrates, maybe a few shrimp or sea anemones. It is much harder to keep the water healthy in a small tank,and the appliances needed for running a salt water aquarium cost pretty much the same (if available) as appliances for a larger tank. I suggest you join a club of salt water aquarists who will be able to start you off perfectly. Your local fish/pet shop should be able to point you to a club.

Where to buy a bristlenose pleco if Petco doesn't have them?

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!
