I have two African Dwarf Frogs in a 3 gallon tank. They came in an extremely small tank (less than half a gallon....my friend bought them for me at a pet store that obviously didn't know anything.) They had the wrong food (beta pellets) and a huge rock....I've moved them to a the new tank about a week ago. They have some live plants and a cave. I have started feeding them frozen bloodworms. They were both super skinny and now one has grown and the other is still pretty small. The big one was getting super chubby....I had been feeding them every day with probably too much food. The last four days I have fed them every other day. The big one hasn't been getting as big but his stomach still does some out when he eats. When I look up african dwarf frogs, he looks like a normal size. The small one has been eating (I have been watching but his stomach doesn't come out too much.) A couple of days ago one of the frogs ran into each other, but that seemed to pass over. Today one had a bloodworm in his mouth and the other one went for it as well....they squabbled...I eventually tapped and they stopped. But they also just went after each other again...with no food. I don't know what gender each is, but I know one is male (I have been hearing singing...) What is going on? They aren't supposed to be aggressive. Help wouldbe great....I'm panicking a bit.
