I bought 2 african dwarf frogs about a week or 2 ago and whenever i put food in their tank, they fight, even though there is enough food for both of them. I thought this kind of frog was friendly, does anyone know what I should do?

Hmm, I've never hard of that problem with african dwarf frogs. They are supposed to be communal. Maybe you should try feeding them in separate setups or putting one in a separate setup altogether.

are they the same sex?

I don't know what sex they are. I really can't tell. I think I'll seperate them when I feel them, thanks for the suggestion.

Go buy a divider to put down the middle of the cage, pet stores have them. Most likely you have two males that are fighting.

Are they fighting or just accidently getting a foot or arm into their mouths? They are pigs who don't see well so it's not uncommon for one to accidently try to eat the other's foot. frogs are the best
