I just two new guppy's male and female, and as soon as i entered them into the tank, the male swam of hiding and my female went straight to my two panchax's and now follows them about everywhere, is this normal? :L
It isn't unusual. They are new to the tank and each fish will act in a unique and individual way. Give them a few days to calm down and I'm sure they'll get comfortable and get into a routine and eventually breed most likely.
