Hikari Cichlid Gold pellets at the moment.
I'm not a fan of those pellets as their basically just fillers, if your a Hikari fan I'd at least use the Bio-Gold line. Nutrition plays a vital role as I'm sure your aware of so with ocellatus being prone to certain disease's I wouldn't skip.
Just keep the nitrates around 10ppm and feed a quality food, there's no reason to do anything other than that.

It wont hurt anything to feed them this for a week to ten days.
I don't really understand hexitima because i don't keep chiclids, but it wont hurt just like doctors give you an antibiotic for a cold, at least it cleans ur system out so the immune system can contend with ONLY the virus not the virus and bacteria parasites and mold, and get overwhelmed.
Just sayin, either way its HITH or HLLE, this food probably would help.
I would absolutely advise against treating without a diagnosis as microorganisms such as bacteria, viruses, fungi, and parasites can change in ways that render the medications used to cure the infections they cause ineffective, essentially building a resistance.
