I have some fish that I started out with and have been trying to sell them. They won't sell. I have lowered the price but still nothing. They are the spined shark, silky spotanous, and a silky fatfish. They are all at $10 should I lower the price more?

Those fish typically sell for less than you're asking. But, before you lower the price, make sure that they aren't sick. Sick fish are much harder to sell, although people in the store will buy them if the price is right!

At the beginning of the game it can be harder to sell fish, because you don't have the advertising and improvements to your tank that would bring a lot of visitors to your store.

Thanks for the reply. I finally sold them all at $5 a piece. Right now I am just trying to earn money and upgrade everything. I did find on magic fish though.

I'll bet I know which one!

My sharks are selling at $9. That is the only fish I have been able to keep alive. All the others have died on me. I am pumping out sharks in all 3 tanks until I get the money for fish research hoping I can keep something alive.

Many cross breeds won't survive at the beginning of the game. I posted sort of a step-by-step guide to getting started in the game that will help if you're having trouble. You can get to it easily by looking here

My strategy for in the beginning is to find the Golden Goldbulb, which typically sells for $60, and breed ten of them and then sell them after they give birth, but before they die on me. Because of this, I have probably sold over 1000 of these guys in total, but, of course, once I find something that will sell for more (after Fish Env. #1), then I'll sell of all of my GGs and breed the new species.
