some of the more spectacularly colored crens would include cobras, xingu1, marms, lents, cinctas(not a huge fan of the green var but still nice), some variants of johanna are really nice, the list is a long one. online is probably your best bet at finding the nicer ones. lfs around here dont get much in other than xingu 1, venezulans, or the smaller species not sure about where youre at though. pros to buying online are better selection and for the most part proper id. cons are not seeing the actual fish and shipping prices. if you buy from a reputable supplier not seeing the fish isnt an issue, i have purchased quite a few fish online (not pikes) and havent been dissappointed yet nor have i had any losses. i say pick what you want and go for it, not what you can find and settle for it. good luck
