All the fish are dead or pretty much dead:(

I dunno what it is. I tried the carbon and then thought which do i do.If i run the carbon than that takes out the meds and if i don't maybe it isn't catching what may be in there.Although no cleaning products or anything has been near it but who knows...

I don't get it. I am starting to think that maybe i should put the regal back in the main tank and feed him lots with some good food and vitamins and run my uv sterilizer and maybe he can kick it. It only seems to be the angels that are breathing super hard. So i don't know what to do.
