In this economy, a fish store would be one of the last businesses to open. More local fish stores are closing than ever before. Tough business to show a profit.
I agree. If a person was independently wealthy and wanted to do it as a hobby that they continually threw money into....it would work. It would be a very difficult way to earn a living. Every single LFS in my area has opened/closed in the last 23 years that I've lived here. One did change hands. The poor fellow worked there every day....he couldn't afford help. He finally was able to sell out. The store has birds and rats, rabbits and a few fish now....I don't know if they are still open.
A fishkeeping passion makes a better avocation than a vocation.
