Platys, Mollies, Neons, Dwarf Gouramis and Cory Cats are all excellent choices. Be sure to not overstock the tank and allow it to properly cycle before adding fish. You would need to contact the Petco in question and ask them directly. Some locations will accept fish to rehome if they have the tank space. Most local fish stores will not, due to risk of disease or parasite transmission.

It sounds like you need to take a trip to your local pet store. The clerks there can help you pick out an appropriately size tank with proper filtration and heating that can help keep Sushi healthy. They can also let you know what water treatments you'll need for the water in your area, as well as test any water you bring it to see if it is OK for Sushi to live in. Pet stores will also carry commercial goldfish food which is a balanced diet that is given to them. It should have feeding instructions on it so you know how much is appropriate to give to Sushi.

The fish that you are describing is Apolcheilus lineatus commonly known as the Golden Wonder Killifish. By looking at the images that were attached it appears to be a male (females are typically less colorful ).

Without an image, it will be difficult to definitively identify the fish in question. It may be a wild guppy. You can request a consultation which will allow you to share images. It is not recommended to add wild caught fish to an existing aquarium without an acceptable quarantine period.
