Pregnant Black Phantom Tetra

[Markloveslisa]

My black phantom tetra may have swimming bladder disease or be pregnant. I need symptoms of both.. Help

You'd be better to google the symptoms. Off the top of my head if it's swim bladder the fish can't keep itself upright in the water and will swim at a tilt or awkwardly, falling to the bottom etc. I guess if it's pregnant it will just look a bit chubby but otherwise move normally.

I thought that.. But it was strange that this female was being pushed upright constantly by a mal I'm new to this relatively speaking.. It's now swimming normally
