For some reason dh told our five year old he can get goldfish. Did he research the needs of goldfish and check we had space for a decent tank, or could afford all the equipment etc? No of course not 
Now I had fish in a plastic bowl as a child but I knew no better.
Is there any other pet I could get that would be very low-maintenance, yet could live a content existence? I have a five year old and a almost one year old, in a small flat. Dh is allergic to cats, and I am scared of snakes.
Suppose I could always put dh in a hutch in the garden..
Any advice would be welcome!
