Water Baby
Aquarium Advice Apprentice
I need help. I have 5 goldfish in an established aquarium but the 3 older fish have been having health issues for the last 4 weeks. I have done all of the water tests and all levels are good except nitrite and ammonia were slightly high so I have today put nitrozorb in the filter. I have tried all of the following to help the sick fish as I initially thought they had a bacterial infection: melafix, pimafix and furan 2. They showed slight improvement with melafix but are now going downhill again. Symptoms in each are different: the worst is moving around on her side (was floating until today but as now sunk further down) and the only external symptom is what looks like popeye (greyish around eyes which are bulging slightly) - unfortunately she hasn't eaten in a couple of days. The next worst has slightly risen scales which are turning darker on the edges as well as the tip of his dorsel fin. He has red spots under his mouth in the gill area and one or two above one eye. He sits on the bottom but is eating. The other sits on the bottom and is eating but has red sores on his underside. This one and the one on it's side look irritated by something and dart around a bit. I have melafix and salt in there now and the redness on the fish seems to be improving but they still look uncomfortable. My other two much younger fish are very healthy. Please help if you can as I am so worried they are suffering. Much appreciated.
