About color, the pic I showed of my c. fowleri, the bright orange one was an anomaly, actually if I recall the fish was temporarily stressed due to very low PH in the tank at the time, after a water change and PH adjustment the color changed back to the usual slightly orange but overall brownish hues as you see in most photos of the species. Their coloration does vary somewhat based on water conditions, lighting and mood but nothing extreme. I have experienced differences in color with other species, bullheads for example, based on gravel color, being almost pure black with a pale white belly in a dark tank with dark gravel to a pale olive back and a bright yellow belly in a well lit tank with bright yellow gravel, so it can make a difference. I didn't mean to mislead anyone with that photo as an example of the species as it's really not, I just thought it was a cool pic...
