Molly With Black Spot

[RBurkett]

Can anyone tell me what this might be.

I bought an orange mollie on the 24th July and took this photo

I have taken some photos tonight and unless I am mistaken the black spot seems to be bigger

Would anyone agree and do you have any idea what it could be?

Please help so I can treat her if she needs it.

Hiya,

Any idea if she is fully mature? It's hard to judge size from the pictures. Regardless, the spot is bigger in the second picture. It looks like it could just be the natural colour of the fish developing, especially as she has black on her tail. Its not unusual for the colour of a fish to develop after being added to your tank, usually its a much healthier environment. On the other hand, I don't have extensive knowledge of fish diseases, is she behaving normally?

It looks as if she is simply gaining her full color as she grows. Do you mind telling me what time of molly this is? She is beautiful!
