I have two African Dwarf Frogs (one male, one female) that I had in a 1.77 gallon tank with a male betta. On Tuesday, I separated the fish from the frogs because the female frog and the fish were attacking each other. On Wednesday, I woke up to the frogs mating and laying eggs (I saw about 5 or 6 at the surface of the tank). I left everything how I found it and when I went back to check on them in the afternoon, all the eggs were gone. I assumed the frogs ate them. On Thursday, I woke up to more eggs in the tank. I took them out and put them in another tank and left the male and female in their tank. That afternoon, I noticed that the female was jumping and biting at the male. The male started floating at the top of the tank and I noticed that he was bleeding from his mouth. I called the pet store and was advised to isolate the male in case he had some sort of disease.

I put the male frog in the container that I usually put them in when I clean their tank with every intention of possibly putting him back in with the female in the morning. On Friday morning, the male was obviously dead. I even prodded him a little and tried picking him up with the fish net but I got no response.

All that to ask, do the females usually attack the males after mating? Or do I just have an aggressive female?
