Hi folks. I've been searching around, but haven't found something quite like what's wrong with my girl for a sorority lady.
She's been acting really listless, hiding on the bottom for a couple days now. She just rushes up to get air and goes back down. Not interesting in eating. She swims...weirdly. Not sure how to describe it, but it looks really strange. I'll find her just lying vertically in the grasses. Her back looks like it is bent a bit. She's dropping weight.
I don't have an isolation tank anymore (had to return it to Petco, but going to get another one today), so right now I just have her back in her changing cup. The other ladies all seem fine, super active, excited about feedings, etc.
They're in a 10g tank, mix of silk & real plants with driftwood that's coloring the water (which has a film on it, but I read that that goes away and isn't harmful). I feed Hikari Gold pellets and I've been them freeze dried brine shrimp ONCE as a treat (but man that stuff is messy so I think I'm just going to chalk it up to a loss). It is heated to around 78 degrees, has a tetra whisper filter.. hrm. What else. I do 50% water changes weekly. I vacuumed the gravel last week, shortly before this all happened.
I honestly haven't dealt much with sick fish. My mom wasn't emotionally invested so she would just let the fish go. She's gone now, so I can't call her for advice. I know as a somewhat newb, I probably shouldn't have taken on a sorority, but I get SUCH enjoyment from it and did a lot of research before hand.
I don't want to do a full water change since the cycle is still pretty new and I don't want to hurt it. As I said, I took her out, but I'm concerned about my other ladies getting sick. I have 4 other ladies in the sorority, no other tank mates.
