You know there is another similar almost identical fish called P. Chalakkudiensis that is being sold as P. Denisonii the real Roselines. I didn't even know there was a false Roseline. I think this is what Petsmart is selling so cheap cause I know there's are really ugly with faded red stripe. I guess to the informed eye there is a distinct difference you can spot besides the faded red stripe.
