In an attempt to circumvent getting a chicken for my 5 year old (they hatched some at school and he was really hung up on having one of his own. We live in an apartment in metro Atlanta so that wasn’t happening), we got a 10-gal aquarium and some swordtails. And I found a new hobby. Anyway, six months later, here I am desperately trying to save the lone swordtail that survived my learning curve (we lost two in the first month, which isn’t surprising since learning that it was probably too many in a 10-gal). He has ick. That’s for sure. I am treating him for that, but two days in he seems worse off. Plus, I discovered white wriggling worms in the tank. I can’t tell if they’re the harmless type or not. I put him in the quarantine tank and cleaned everything thoroughly, including the substrate (probably a bit too thoroughly). Did a massive water change and cleaned the two live plants that were in there. Now he’s hovering at the surface. He hasn’t pooped in a few days either. I’m at a loss. I use Prime for my water changes and I’m treating him with Super Ick Cure. Other than that, I haven’t added anything to the water. Temp is at 78. I have dip test strips. Here are the readings as of 10 minutes ago: GH: 0 KH: 0 pH: 6 NO2: 0.5 NO3: 20 Ammonia: 0.5 I know the hardness and pH are not favorable for swordtails, but I’m not sure about adding things to offset or “fix” the issue since I’m already treating him with ick meds. Pics attached. Help!
