I agree that they are prone to bacterial infections after a territorial dispute; if they get a flesh wound as well they will often get fungus.
Many of the zebras exported -a couple of years ago at least were extremely exposed to ichthyophtirius (ich). Mine had it within 5-7 days in the quarantine tank. They were treated and i did not lose anyone.
I think this applies to WC especially, of several reasons, one being poor handling and care from the catcher down to the hobbyist.
Another is tetrahymena, i lost one a few years back, i found him/her lying in the open and it had a whitish film covering its head, which was not present or noticeable while he/she was alive. This one was WC.
Why ichthyophtirius and tetrahymena? Well before i bought my first i was warned about this and spoke to a couple that also experienced it, so when it happened to me it left me puzzled a bit, because i did everything by the book...
I am trying to figure out if there is any disease that repeats itself for zebra owners and for WC vs tank breed.
Historical speaking... what kind of experience has zebra owners had regarding this issue
So that myself or anyone else is caught off guard, so to speak
I would like to point out that certain diseases are typical for WC and others for tank-raised fish.
Very often diseases break out when WC and tank raised fish come together in one tank.
