Females and other fish

ADF's don't harm bettas on purpose they are basically blind and have tiny claws no teeth. My betta and adf get along, but if the frog thinks there's food infront of him/her he/she will try and snatch it. So it is possible but they def don't go looking for the betta. Also as they age they lose their claws I think..from digging in gravel

I strongly recommend this article by OFL, but keep in mind that this is for ONE fish in 1-4 gallons. http://www.bettafish.com/showthread.php?t=115758

How often do you do partial water changes? With that many fish, you need to be doing partial changes at least every other day and a 100% once a week unless this tank is heavily planted.

Get a gravel vacuum and 5 gallon bucket and clean about 25%-50% a week and atleast one 50-80% change/month.
