Here's a picture of 2 of the other fish that seem fine..

It's silver sand, not sure if that's different - this one https://www.swelluk.com/swell-aquarium-silver-sand/

Contamination is possible, I am always careful and the other fish seem fine though. Also it seems to kill them slowly one by one. I've been doing extra water changes just in case anyway. I'll try and get a picture of the others today, I'll attempt a video but he was swimming normally again...

Hi there, I posted last month about unexplained Cory deaths - (https://www.fishforums.net/threads/help-corys-keep-dying.464480/page-2#post-3971864). Basically one by one, the Cory's would start acting strange - breathing rapidly, lying at strange angles and with some swimming oddly (sideways...

That's interesting. I've fed them for years and it didn't even cross my mind. I'll definitely stop, hopefully the rest survive. Thanks for the advice

I'll definitely look into buying a powerhead, wouldn't hurt to have some extra flow. Thank you for the advice. The sand is no more than 2" deep but I think has still developed some anaerobic pockets. Not sure what to do about them

Flow is decent and oxygen should be ok, have an airstone on periodically. They are on sand which does get vacuumed but its possible there are anaerobic pockets in the hard the reach/planted areas as the sand is quite fine and relatively deep. Could that potentially be the issue?

Yeah I've considered stock maybe being the issue. They were bought at different times though with the oldest being about 5 years old - but still from the same shop so I guess it's possible. I've considered treating the tank but like you said its hard when you don't know the issue and I don't...

Water is pretty soft here and pH usually sits around 6.5

No new fish or anything when it started happening, maybe a couple of new plants but nothing major. All other fish are acting normal, look healthy and haven't lost any. I'm usually very careful and don't use any chemicals in that room but it's possible. They have died one by one over a long...

Did it stop after one? Unfortunately it seems to be killing all of mine one at a time :(
