Back in the late 1950s when I started keeping fish, it was known as live bearer disease.
I had not seen it in my tanks until 3 years ago during a heatwave, and my beani, got the "ducklips" acute form. Tanks that I normally kept in the mid 70sF were up in the mid 80sF that summer.
When it was known as live bearer disease, live bearers were the most inbred and hybrid fish in aquaria, so I have been wondering if the neo-proliferation of hybridizing cichlids, has unwittingly brought it into this family. The more research I have done into the latest semi epidemic conditions seems to have been parallel to the flowerhorn inception.
When you hybridize a fish, you also may be co-hybridizing all the micro-flora and fauna inside the fish.
