Should I be concerned about my guppies?

Question
I have four tequilla guppies and they have been acting very strange since I got them last week.  They swim up and down the side of the tank.  Should I be concerned?

Answer
Hello!

I wouldn't worry too much, they are probably checking out their new home! However, if you see any other physical or behavioural abnormalties, let me or another expert know. Some things may include- fin clamping, white spots or tufts on bodies, bloating... the list goes on and one.
If you want to see some disease your fish can stumble across, I highly recommend this website:

Hope I got the address right and I hope this helps!
