I have 2 Fronts listed on Craigslist for local sale. I have had a couple of replies and both suggested that my price is unreasonable. The fish are 2 years old and about 6" long, nuchal humps starting to develop. I listed them for $60. each. Judging from prices at Live Aquaria and other sites, they're selling 2" for $25. Are my expectations too high?
