They're all in the sorority! Dido is definitely female.
Some fighting at first, albums being the instigator, but as soon as she got nipped she went and sulked in the corner, making her the low man. Venus and Dido seem to be codominant, and Andromeda just keeps to herself. In the end only Albica and Venus got any fins nipped/torn, and they're both very minor. Albica is still hiding but the other three are pretty social. Aliquis has been checking out the ladies from his tank, which is right next door. The girls make him look HUGE!!!
