My rival ADFs

Question
Hi Christy-
I have an 8-gallon Biorb tank. It is a mature tank with: 6 tetras, a balloon ram, 2 panda coreys, 3 whiteclouds and 2 African Dwarf Frogs. I got the frogs several weeks apart, as the tank was cycling and new and I didn't want to fill it too quickly. I have had them both for several months now. I feed them at night, when they're most active. They get a chunk of frozen bloodworms.
I have begun to notice that one frog is hugely fat and theother is emaciated. Last night, when I fed them, I watched carefully. As expeected, the fat frog dove right to the food and the skinny frog barely cared. Eventually, the skinny guy came over to get his share, and fatso attacked him. Clearly, frog A is a bully, so frog B gets no food. The weird thing is, I tried putting 2 chunks in at the same time in different places, and skinny frog only tried to eat the same chunk as fat frog. He didn't even notice the other food. How do I save him from starving to death? Does he need to be removed from the tank? If so- what kind of smaller tank would be good for him? Small, big, filtered, unfiltered, etc.
Thanks so much!

Hi Rebecca
That's strange, I've never heard of them being aggressive or territorial to one another.  Are you sure you have 2 African dwarf frogs?  A lot of stores mislabel African clawed frogs as ADF's.  Clawed frogs are known to be more aggressive.  

Another possibility, you have a pregnant female.  Females are bigger then males, and I have a link I'm going to post, but the pregnant females look huge compared to the males.  But if the one does look real thin, it might be a good idea to rehome him.  A 5 or 10 gallon tank would be fine(10 gallon set ups seem to be a lot cheaper then the smaller tanks).  Filtered, and you could use some of the filter media from your current filter in the new filter to pretty much instantly cycle the new tank.  

Another thing I remember reading, use a turkey baster, and put the blood worms/food right in front or near each individual frog.  That way they don't have to hunt around for the food, and maybe the smaller one can gobble it up before the other one notices :)  Here's that link:

On the left they have info, the first is about African clawed frogs, the bottom half African dwarf frogs.  There's a photo of a pregnant one to compare yours too as well.

Hope that helps and good luck with them!  Don't wait too much longer though, they do have a tendency to starve to death, it's quite common with them, though usually due to the fish in the tanks getting the food first.
Let me know if you have more questions.
