I thought that everything had turned out fine, as far as no compatibility problems while accumulating my small/medium sized Africans. Although today I noticed that two of them have been visibly bitten Is this something that is normal/bound to happen, or does this mean I need to make some changes? Also, I've been advised to feed them everyday in order for them not to take out their hunger on each other, so am I doing that right? Answers much appreciated.
