Black molly - orangish red tip of fin

[Drunkhacker]

I have a black Molly and a dalmation molly , both the most dominate in the tank , 72 gallon . They recently developed redish coloring only on the tops of their top fin . Photo should be attached . Can anyone tell me what this is. ? Regularly maintained , ammonia 0 , nitrite 0 , nitrate 10 , recently added lots of plants but this redish was before that . The 72 gallon tank is well stocked , maybe 60-65 inches in total . I have an fx5 filter and check all levels daily .

Anyone have an idea ?

Have the fins always had white on them or has this just developed?

 

[Drunkhacker]

The white on the Dalmatians fins has always been there , only the orange / red is new

What is the ammonia level in the tank?

Do the fins look frayed at all? I couldn't tell from the picture

My Dalmatian Mollies have blue and yellow/orange pop thru them in spots and streaks randomly.... As they age colors change.... Even in a 6 mth time period...
I had a Dalmatian Molly I purchased mostly white with black spots last September. Now she's almost all black with a few white streaks on her with orange speckles.

My male Sailfin Black Molly (looks almost identical to yours) has an orange line on his tail too... Looks like Orange eyeliner on his tail...
I believe it's perfectly normal... Just color changing as they mature.

I've got a Lyretail Molly who's marbled black with a bit of white. I agree with ocminpin - he's changed coloring (with regard to black and white ratios) and also developed tiny orange specks along with an orange border on the edge of his dorsal fin about 3-5 months after purchase. Just the result of genetic background. No worries. (Doesn't mean I didn't freak out.)

EDIT - Just to clarify, the Molly has changed coloring, not ocminpin (so far as I know!).

I also have a black Molly whose fin tips are changing colour-to a greenish hue!

ROTFL... You mean yellow red and blue polka dots aren't NORMAL?!

Thanks for all the info ! Only remaining concern is the same color showed up on 2 different fish at around the same time . Just a coincidence ?

What other fish? My mollies change and darken all the time. I don't even realize how much until I look at pics
