Question to your quarantine methods to avoid the spread of Columnaris. Thanks to your info and some past posts that I've read, and also doing a bit of research regarding Columnaris. My understanding of this dreadful disease is that it is highly contagious and can survive in a single drop of water and even some cases mud. So even though you are quaranting fish for 2 months, if the new fish just so happened to be already carrying this disease, wouldn't your quarantine system also be affected, and when the time came to transfer the fish into gen pop it would still be carrying this disease?At this point, the bacteria is in the tank, and whether the immunity of the other fish is strong enough to ward it off is anybody's guess.
If the water temp is above 82'F, I'd slowly reduce it by a couple degrees.
I don't know what the other fish are, but these northern Mexican Herichthys do not need higher temps.
I've kept them as low as high 60s. (a list of other species would help determine how far you can go).
I must admit after I experienced Columnaris, I sanitized the entire tank, all gear water touched, and expected any other cichlids in the tank were going to be goners. (it seems to sometimes be species specific)
But treating with antibiotic effective against Gram Neg bacteria could ward off the worst case scenario.
This is the one disease that prompted me to give all new fish be given a 2 month quarantine before putting in the main tank with others.
To me it sounds like corona virus to fish and the only way for fish to survive and live with this disease is to create a vaccine and have them all vacinated.
If you have any advice/suggestions on how to bomb my tanks to wipe this disease for good that would be much appreciated.
I'm just thinking ahead in case all my stock is affected and died, what do I need to do to my tanks and equipment to restock and start over, but I also don't want to accidentally contaminate any other systems I currently have running. Than I get thinking, well what if my new fish are carrying this disease and all my time and effort spent sterilising and cleaning my system and equipment was a waste of time because the new fish have now infected my system.
This disease has me stressing and confused.
