And I'm happy to report that they've all finally stopped bickering! Turns out that Tiny Town was able to become the most dominant, so Fat Mary quit bullying the others.
They all clumped together waiting for food and like to swim in pairs now. I'll still look into finding some floating plant to go into my tank as a precaution though! They're so cute! X) They all charge to the top of the tank in a giant pack as soon as they see my finger!
Here are some crappy iPhone shots of them and the tank! And more suggestions cover-wise for my aquarium? I know there's quite a few silk plants, but I really want to make it all planted in the future :)
