Local price matters only to local buyers; if a buyer is willing to have a fish shipped then you must compete with whatever prices that buyer can find from other sellers in other areas of the country. If other MFK members are finding similar fish for $40, $80...why would someone pay you $175 for yours?
Does the fish have sentimental value to you? If so, that's nice...but it doesn't affect what a stranger will be willing to pay for it at all. Did you overpay when you bought it? If so, that's too bad...but it doesn't affect the fish's actual market value either.
I buy and sell a lot of non-aquarium-related hobby merchandise online, and I'm always hearing "I just want to get back the money I have into it!" from chronic over-pricers. Makes me laugh...but it doesn't make me inclined to overpay just because they did.
The pics you have posted show a nice healthy-looking fish. Price it fairly and sell it quickly before it deteriorates from the overcrowded small tank in which you have it; if you dig in your heels and stubbornly keep the price too high, the fish won't sell...but it will become less attractive, less healthy and eventually worthless.
