The discussion about Apisto behavior in the "sleeping hours" thread reminded me of something:
There is a behavior I have seen that seems to be an early indicator of internal infection in Apistos. The fish hover in one place slowly undulating the body in an eel-like motion, similar to a snake pushing food down its throat to the stomach. I have had agassizii, macmasteri, and regani-group Apistos do this at various times over the past 15 years, and in all cases the fish got other symptoms within a couple weeks after the undulating behavior started, such as appetite loss, bloating, or rapid breathing. I never saw Camallanus or anything that looked like external parasite symptoms on any of these fish, but some did get body sores that might have been from Mycobacterium. In most cases they died a few weeks to months later. Have others seen this undulating behavior? It looks quite different from the "shimmying" behavior that fish with skin infections (ich, velvet, costia) often do.
