5teady, personally i cant remember ever having a disease problem with cichlids, its no where near as common as livebearers getting sick (in my experience), i think i had a Convict with fungus thats it. Never had any sign of disease in my malawi tank
BUT.... i have lots of different fish, and anyway, here's my advised list of what to stock (others will have their own views obviously)
Bog Standard recommendations, covers a lot of different common problems
Protozin
Melafix
Pimafix
Internal Parasite specific meds (i used to use Flubenzole, not sure if its spelt right, now i think Wormer Plus is the one)
Added reasurance if you can afford it (i recommend this and i keep it myself on top of the above list)
Myxazin
I also have used Interpet medications in the past and found them okay
ALso, being a livebearer keeper i suggest a supply of dishwasher salt (seriously)
EDIT: i am not completely sold on the effectiveness of Melafix and Pimafix but you could say that about almost any meds, but i like what i hear and read about it, and i have used it in the past with no problems and its "helped", i just have never had to rely on it as a first line action against disease, its a bit more "first aid" i think, very good for wounds and a very safe meds by all accounts for your fish and tanks (from what i hear), too expensive in my view!!!!
