Thanks elly for your reply!

Carrier of salmonella, wash! I did not know that ... I imagine that there is no way to know if a frog is carrier??

An aquaponics system is a self-sufficient system, where plants gives good water for fish and fish excrement turn into nitrate, good for plants. My system is in the house, so no worry for the cold winter of Canada. The frog would live in a terranium, we would go out a few times a week to eat the insects in our aquapony system, in addition to its diet.
