African Dwarf Frogs?

[Uabassoon]

I have two, their names are Pac Man and Frogger. I've had them for around two years I think, they are pretty easy to care for. I have them in a 2.5 gallon tank, they do not need a filter although I have a small filter for their tank. I feed them bloodworms twice a week and they get "frog and tadpole bites" on days when I don't feed them bloodworms. I currently have a male and a female, but I've never seen any eggs from them although I have seem them "making love" before. They can live for around 7 years and full grown they can get up to 1.5 to 2 inches.

Here is a picture of their tank.
