The biggest factor that plays into fish susceptibility to disease, IMO, is their origin. Neon tetras have a high mortality rate because they're genetically "watered-down". Some fish, like otocinclus catfish, are fragile because their wild-caught and the methods used are often very traumatic for the fish.
EDIT: I've had virtually ZERO opportunistic infections (Columnaris, Saprolegnia fungus, etc.) since installing a quality UV sterilizer.
FYI, male bettas make GREAT tankmates for community fish. You just can't keep them with fish that are notorious fin-nippers because they'll get abused and you, obviously, can't keep them with other male bettas.
Man this is a blast from the past.
How the hell are you???????
