I recall years ago being told that the stability of the NGT depended on whether they had clear or black fins but I can't for the life of me recall which way round it was.
Plus I never really had a problem with stability with the ones I had so I'm not sure that this holds true anyhow
I've actually been tempted to buy back one that a fellow member has lol.
I've had a few campbelli over the years and I have never took note of any varying fin colors,to be honest.My areas of attention were the range of colors(I've had some that were almost orange)and getting them off of live foods.They are extremely stubborn in my experience.

ITHE BLACK CAPE! lovin it K krichardson . Beautiful piece. It’s either fighting crime or causing it. Lol. Something different between the two. It’s not due to mood, lighting, or water param. I suspect it’s permanent. Look through some wild dat photos I put in on the other threads. Some sport black cape too.
