As some of you are probably aware, I recently caught some baby minnows,sticklebacks and wild trout for my back garden pond. I have around 50 in this pond(mixed). Due to their new environment where no predators exist, I'm just wondering how long these fish will live for, how big they will get and how many more will I eventually have? Of course the winter months will take it's toll, but nevertheless they are fed twice a day and they receive almost as much TLC as my tropicals. The water is purified via a pump and filtration unit-this is mainly for the abundant plants the pond has.As I say almost as much TLC.
