I read some where on the forms that there is 7 basic fish to get! DO you know what they are? I forgot who posted it. Are they really needed to breed the fish!

no, they are your goal. they are the ones you are going to discover, you can get them by keeping track of every speices and fin combination

Thanks for the tip. I was wondering what or how to get them.

you can look at the Guides here (PT guides)

I will do that thanks
