but what if the pet store does not have a tank for these fish at all? Anyone heard of a fish broker? Probably not, but maybe that is possible. Also, you could try selling them on Craigslist. Maybe take one of them to a pet store first. Ask an employee to identify it for you, once complete, accomplish searching there needs and care, then, if you are sure you don't want them, you can try selling them on kilojoules or Craigslist? But make sure to take them to a quality pet store and find them a good, quality home. Good luck!!!!
