kiburiburi



I don’t know what to do, I don’t want to lose her; she’s been here for so long (she’s even lost an eye..). I have her in quarantine right now. None of the other males and females look sickly; their coloration is fine and they’re all swimming around.
Now, I have a guess as to maybe why she’s ill? I recently refilled the tank, so I’m wondering if the pH is off?
I won’t lie, I don’t actually have anything to test the pH. I know, that’s really bad...maybe they’ve all gotten accustomed to the water they’ve always been in though? Because they’ve been fine and I’ve had them for years..I don’t know I’m sorry, anyways: maybe she’s just old?
But then again, why is it just her? And why is it just her tail? And her scales are sticking out? She’s also laying on the bottom, but occasionally swims a little bit...
Any help would be much appreciated.
