The cost for one of my Betta Fish is 20 dollars. This covers the shipping cost and materials. I pay for the medication and tanks by myself. I know you are paying more money then if you went to a pet store, but you are opening up a spot for a new fish to be rescued. You are also getting a fish that is healthy and free from diseases that you would have to pay for yourself. If you cannot adopt, please share this rescue so I can get more people to adopt. Thank you!
