A friend of mine decided to get some fish but came home from petshop with blue marron. I had to laugh because I knew she chose them because they looked pretty. Some months later she says she had all these buckets full of baby marron and didn't know what to do. I told her to call the pet shop. They sent someone around and bought most of the babies. We didn't know that the parents could eat the babies.
I've been thinking of goldfish lately either in a pond of tank inside. If I have the pond outside more than likely snakes will come. There was an old pot I had that we waterproofed and it had fish in it for years until the flood.
