Beta Fin problems

Question
Hi.
I've had a beta for the last few months, it's a 3 gallon (I think) with one (fake) plant.  I do clean the tank once a week and am using a water conditioner when doing so.  The last few days I've noticed the top fin is looking a bit off. It doesn't stick straight out, the end seems to be curled to one side (almost forming a little pocket).  Other then that, everything seems fine.  He eats normally, is active and isn't showing any other signs of illness (as far as I can tell).  Is there anything I can do to fix this?
Thanks
Ashley

Answer
Hi Ashley;

It's probably just normal for him but watch it for fungus or other signs of disease just to be sure.
