Does this look normal/healthy?

[awelcome]

Sorry for the kind of gross subject... just wondering if this is a normal healthy dart poop. This is how they generally look though usually a bit more solid in color, and he goes most days that I have found (he likes to leave them right up front on the log or rock for me to whisk away). Pill shaped, and slightly firm which I know to be good signs, but what about this ombre effect? Dark on one end, redder in middle, and orangeish on the other end? Thanks... from a paranoid new frog owner lol. And I gotta say... I am quite surprised at how LARGE they are... the pet store person said they would be tiny. Oh and someday perhaps I will look at a fecal test, but for now I can't spend the extra money.
