Please help my fish
I’m fairly new to this hobby, however having learned the hard way, and losing many common/comet goldfish along the way…… I am still confused as to why my goldfish can be happy one day and listless the next day. We’ve had our 3 goldfish for over 2 years living in a 5.6g tank, 1 died recently last month so I rehomed the surviving 2 goldfish into our 10g sump.
Admittedly I panic and try to administer either Api General Cure or Hikari Prazi-Pro because in the past I’ve watched each of our goldfish start out with sunken bellies then eventually die. After going to many pet stores and reading almost every forum I can only assume its wasting disease and have been told these fish are “usually” feeders preferably not kept as pets.
But after 2 years of hopefully “healthy” living I assumed our comets would be long term pets….. till last month our white and red goldfish became sick and died. And now that the 2 orange survivors have been living in a 10 g sump, one started exhibiting the same listless behavior. Fins still up he just seemed not interested and no stringy poop but could see what I assume was the start of a sunken belly.
Quickly took him out in fear of disease spreading and put him into a 1 gallon tupperware with an air stone and 1 bag of old filter media. To my amazement he perked right back up and started swimming and eating. I got excited and went out bought a 15g tupperware, same air stone and 1 filter sock from the sump. By that night he was back on the bottom sitting lifeless.
Now that I’ve read your forum I see maybe its been my mistake by transferring the fish from home to hospital and only thinking “zeroes” are good for all water parameters actually may have stressed him out more. He was listless then became folded and when he tried he could only swim in spirals? Two days later he has passed….. nitrates poisoning or levels too low?
Sorry for such a lengthy post but I’m still confused as to why a healthy goldfish can turn sick so fast, the other habitats in the tank are all still healthy I HOPE!! No new fish introduced. Water parameters are 0 Amm, 0Nit, and 20 Nitrates. Ph 7-8 range. Try to do weekly tank cleanings but usually becomes every 10 days.
Hoping for some insight as to why my goldfish always seem to develop some sort of parasitic disease? Even after 2 years without problems? Ultimately i want to know if I’m doing something wrong and how I can make our last goldfish live for years to come….
Thanks in advance,
