Ok. Then consider a fasting period. Still not better then the measures I mentioned.Yes, it's still acting normal and eating aggressively.
If they are acting and eating normal, they are not sick. Two reasons they can get fat. They are fast swimmer and can out compete for food. What other fish do you keep with them. You have ripped females that are egg bound. How large and mature are they.

I seeI did fast them for a day, and I've started feeding hex shield. I'll look into those other meds you mentioned.
