So I recently set up a new 10 gallon tank. It's gone great so far and I love how it turned out. I have in it 8 CPDs and 4 Scarlet Badis. Everyones eating and aside from some stress from shipping everyone seems healthy. After staring at the tank for awhile it feels a bit empty though. I definitely need a centerpiece fish or 2. I'm thinking dwarf gourami but have been hearing mixed reviews on their behavior. Ideally I would like something blue, to counteract all the red that's currently in there. Any suggestions?
