My Pictus Cats are dying!

[Ghost Knife]

Firstly, let me say that I have not changed anything with my tank and it has been cycled for months. I have had the same 4 Pictus Catfish for about 6 months or so. Today one at a time three out of the four went limp and died. Why would this have happened when I have changed nothing in the tank? Did one develop a disease inherit to their species and then the rest got it? There is 0 ammonia, the temperature is 78 degrees, PH is about 7. Anyone have any ideas why this is happening?

3 dish all died today?

Check for anything that could have poisoned them, like bug spray or a bad batch of fishfood. Also check the filters and gravel for a rotten egg smell.

I did that and nothing. I also have been feeding the same brand of fish food for a long time as well. I checked on the fourth one this morning and he is still ok. I just don't understand what happened at all. I still think it was type of disease.

This may not be the case, but for future refrences, pictus catfish do not know when to stop eating, just like goldfish. If you over-feed them, they will not stop eating. This may cause them to become bloated. Make sure not to over feed them.
