Hi
I doubt that at 2 in. an Angel can start to lay eggs but I'm relatively new to Angels. But it sounds as if they just had a really good meal. OR they might be a bit bloated and possibly constipated as well. You can try to fast them for a day or two and if that doesn't seem to work I've heard that a boiled then peeled Pea would do the trick. OR worst case is that they have parasites and that is why they appear to be egg laden and fat.
