Hopefully, this is the last of my bad aquarium news for awhile: Unfortunately, this bacteria/disease that arrived with my galaxy rasbora/celestial pearl danio and started taking them one by one is horrific. It has now wiped out all but 3 of them overnight...in a medicated and perfect water parameters (as of last night) tank. Awful...I removed 6 this morning. Deceased. The rest must have already been scavenged by the shrimp, or soon will be. The water this morning was showing a very slight ammonia spike, no doubt due to all the dead fish, so I had to do an emergency 25‰ water change before the healthy fish (all my neons, catfish & shrimp) got poisoned. Seriously thinking I need to find a 4 or 5 gallon aquarium to set up a hospital/quarantine tank before ever adding new fish...should have kept that spare filter after all! Itll be at least a month now before Im confident the disease has run its course in my tank and its even safe to consider adding any new fish... The only good news I have to share is @thekidlet spotted ALL FOUR of our Otocinclus catfish AT ONCE, meaning we never lost one as Id originally thought. The mouth bones I found must have belonged to the Corydoras sterbai catfish we lost in his first 24 hours over a week ago. Closely monitoring the tanks water parameters and inhabitants to hopefully keep every non-galaxy rasbora in the tank alive and happy. Im not sure the remaining galaxies in there will make it or not. They both already have the skin lesions consistent with the first stage of columnaris infection, and as you can see, it leads to their demise very rapidly from there. Thank goodness it doesnt seem to be spreading. From my reading, since its ever-present in aquaria water, its basically something fish fall victim to when theyre stressed (such as from importation, netting at the fish store, and being put in a new tank). It also strikes genetically weak fish, which this batch may have been, or this species in general may be. Its still fairly new in the aquarium trade, discovered in the wild in 2006 or 2009.
