Third day of treatment (Furan-2 + Kanaplex) for a columnaris outbreak in my DT that was entirely my fault - wasn't careful enough with my equipment and contaminated it due to a pair of new fish that succumbed to it two days after purchase. Four of my old fish showed signs of it within a day of when I suspect I contaminated the tank. So I've been shuffling fish around between bins, dosing meds, and doing close inspections of everyone involved.
Old fancy goldfish - the rapid deterioration of his fins has stopped and the inflamation around his scales/gills has gone down.
Female hoplo #1 - Large legion on her side has stopped growing and is healing.
Female hoplo #2 - Adipose fin decay has stopped.
Female hoplo #3 - The worst afflicted, lost all four barbels within 24 hours and passed away in quarantine earlier today.
4 other hoplos, black moor, ranchu goldfish - No signs of illness yet. Behavior is normal.
On the upside of things, I was forced to run out and buy two new aquariums to house a shipment of new fish that I had ordered over the weekend before disaster struck. I used up all my sterilite bins and buckets and my QT for sick fish, so I was out of space for the new guys, so I got to set up a 29 and 10 gallon
Here they are in quarantine;
So just remember folks, always quarantine new fish and be extremely careful with your shared equipment - I was disease free in my big tank for almost 2 years, and the moment I became lax in my practices, I had a disaster on my hands.
