HI guys I've had a RTBS for 4 weeks...he was tiny when I got him...growing nicely now but I've noticed the tip of the dorsal fin is white...looks and acts totally fine otherwise.... Could it be something to worry about?.... Thanks

Loss of color usually means the fish is stressed. How big is the tank and what are the parameters of the tank

Its a 3ft tank...0 ammonia.. 0 nitrites.. 10 nitrates.... It's literally the tip of his dorsal fin

Oh sorry I thought you said his tail was turning white my bad. White on the tip of there dorsal is just part of their coloration. No need to worry he just maturing.

If your meaning right on the very, very tip, it's the norm for RTBS's and nothing to worry about. Look at some good quality pictures online and it should be noticeable.
