I recently bought a yellow tailed damsel (Chrysiptera parasema) for my 24g Nano cube. I know damsels have the reputation for being evil and am aware that I may have to take it out at some point, but even though they are so common, I really think it is what of the nicest looking fish available (Especially under my LEDS, it almost seems to glow). No other fish that I know of matches the intensity of their blue coloration. I currently have a well established pair of snocasso's and a neon goby. My question is, would I be better off having two yellow taileds so they spend most of their time pestering eachother or am I best to stick with the single that I added yesterday? Thanks for any suggestions.
