For those of you who have kept flagfish, what do you keep them with? I had two, the last two the store had at the time. They did not make it out of quarantine. I want to get more, as they have now restocked, but I don't know what will be suitable to keep with them. I had three golden topminnows, but two of them only lasted a few months before succumbing to some strange illness where they were corkscrewing around the tank before they died. They were dead within 24 hours after symptoms showed up. The tank needing to be stocked in question is a 20 gallon high, so it can't hold much, but I would like to have something in it. It's currently housing the one remaining topminnow and my two goldfish fry. If it can just be flagfish together I'm okay with that, too. I've heard they can be somewhere between just showy and downright aggressive. Just interested in everyone else's experience.
