Oh, forgot to say that I love, love, love that Findex feature too. I have already managed to have some uncommon fish be born and can easily see how to make more. That is SO helpful!
. I did somehow end up with a dead fish and don't know why or what kind it was but all others are healthy and fed, so I hope it will not happen again.
Am researching environment because I remember that must be fully researched for the rare ones to survive.
