Illness & Symptoms
How long have you had this fish?
The 3 new corydora I had for about 2 weeks till they died only one new corydora is alive now and the 2 balloon Mollies that died I had for about 3 months
How long ago did you first notice these symptoms?
The balloon mollies died out of nowhere I didn’t see any noticeable symptoms but I did notice one of them had white poo after a few weeks from giving birth. The corydora on the other hand were swimming frantically for a few days. I thought this was just due to stress from getting a new home so I thought it was normal but 2 weeks later 3 of them had died
In a few words, can you explain the symptoms?
Have you started any treatment for the illness?
No because I am still trying to find out the cause of their deaths
Was your fish physically ill or injured upon purchase?
No although the corydora were freshly shipped in and were probably highly stressed but that doesn’t explain the balloon Molly deaths
How has its behavior and appearance changed, if at all?
No the behaviour of the balloon mollies were not out of the ordinary they were eating fine and just doing their thing, the new corydora were glasss surfing and seemed to be stressed but I thought they were just adjusting.
Explain your emergency situation in detail. (Please give a clear explanation of what is going on, include details from the beginning of the illness leading up to now)
I purchased 4 new albino corydora and suddenly fish start to die I don’t know what the cause is since they have no visible sickness to them although the white poo might’ve been parasites but I’m not sure since it was only one fish had white poo and the others had brown. I’ve been monitoring the surviving fish and none of them have white poo. All the fish that had died didn’t seem to be bloated or have sunken bellies.
