Dark shadow inside Balloon Molly

Hi,

We purchased a balloon molly about 2 weeks ago and have notice that there is a dark shadow inside. She is pretty chilled out but active and eats well at feeding time except for a couple of days now she has been ramming into the other balloon mollies, none of which are males. I haven’t noticed it or been able to see it on my other lighter balloon molly in the tank.

I definitely know she female and I’m not assuming she has babies inside but I’m just wondering if this is normal?

 

I think babies would be a safe bet. It's harder to tell if a balloon molly is pregnant because of their already extended belly

 

Well, with light colored balloon mollies, the guts or a pregnancy can shine through the skin. I wouldn't be worried about it.

 

She is pregnant, pregnant females get aggressive to protect their babies.

"Yes" and "no"...
It really depends on the individual fish wether she becomes protective or not.

At least in my experience
