Chubby Swordtail?

[Ir3land]

Hi everyone! I noticed something strange with my Swordtail Spice, when I went to check on her one morning she got this gut. Unfortunately my water parameters aren’t the best as I realized recently that my tap water has a lot of Nitrates , however I am now getting my water from a different, healthier water source. Any idea what’s happening to my fishy best friend

They are livebearers, so pregnancy seems like a possibility

That’s what I initially thought too, there’s no other swordtails in the tank but when I got her she was housed with a bunch of them, so it’s a possibility she just was like “it’s time”. I’ve been seeing a little bit of black near her backside which I understand is a gravid spot? I’ll keep an eye out on her.

Yup, probably pregnant. But could we get a pic from top view?

Yeah, they are related to platies, so assuming they can store packets of sperm for some time as well. I don't know about the shippers and fish farms, but i do know that i almost aleays see males and females mixed in the same tanks at stores, so yeah, good chance!

Of course! Gimme just a second
Unfortunately right now she’s decided to hide in a cave
Finally snapped some photos, sorry they’re not the best quality

Hi everyone, I unfortunately think spice isn’t pregnant but has swim bladder. She’s been at the top of the tank but in a sideways position. I unfortunately don’t have a picture at the moment. Any advice is appreciated
