A group of fish called bristlemouths apparently are the most common vertebrate on Earth, number potentially in the quadrillions of individuals. By contrast there are a mere 24 billion chickens. Are there bristlemouths in any aquariums? With this revelation it seems like they might make an interesting exhibit; also because they are bioluminescent. http://www.nytimes.com/2015/06/30/s...p-stories-below&WT.nav=top-stories-below&_r=0
