Do you fancy a joint venture, $200K a year for you and $300K for me......well I do have travelling expenses!We have something called petbarn here, it's pretty bad for fish but some of the country stores seem a bit better. Generally goldfish and a very basic range of tropical. I've never seen anything even close to being rare or unusual in them , I'd be surprised to even see a GT or firemouths occasionally. Usually they have a bunch of empty tanks and the rest filled with boring unhealthy looking tetras and guppies.
The owner of the whole business is on a tv show where you go and pitch a business idea to him and a few other rich entrepreneur, if they lie them they invest.. In my daydreams I'm tempted to contact him and see if he will hire me as a national aquarium manager for $500K per year!
It's worth a try, if they did it properly they could really take over the local aquarium trade and their buying power would be incredible so they could get prices down. As it stands no one with even the slightest knowledge of fish would ever buy anything there.
We have a show in the uk like the one you mentioned, it's called "dragons den". It's hilarious. Some people go up asking for shed loads of investment for the most useless business ideas you've ever seen. The dragons just rip them apart.
