In the spirit of tying to show the reality of fish keeping, I try to show my mistakes, as well as successes, and…
this has turned out to be one of my major mistakes of late.
The normal quarantine time duration for “any” new fish I acquired in the past, or of late, is usually at least 2 to 3 months, dependent on number of observation factors.
But……
Because in observing these latest fish, all seemed to be (at least on the surface) healthy, at 6 weeks in, so I stupidly cut short the time I usually extend, and am now paying the price.

Within a week of adding the new ones, my normal tank residents (cichlids) started kicking the bucket.
One death the day before yesterday, 3 floaters when I got up yesterday, again this morning, at least 5 cichlids were corpses by 7 am, and another 2 this afternoon.
I took the ferry to town yesterday to pick up Pazicuantrel,

because I live on a small fairly remote island, and there are no aquarium stores, of even a dog or cat pet shop on Taboga with to access medications here. So a trip to the vet in Panama City was warranted.

Some may think because I collect wild fish, this is a special case, and QT is not that important,
but…
any new fish has the potential to carry stress induced diseases in the form of opportunistic bacteria and viruses, due to pressure caused by transporation stress issues, and simply new changes in habitat by being put in a new aquarium. These phages don’t need to be overt pathogens, just opportunists.
Different pH, different water harness, different tank mates, can all contribute to a stress induced immune system compromise

Just because an aquarium shop is located in the same area, doesn’t mean, the way they treat their water, is the same way one or another aquarist treats theirs.

The question I ask myself today, is whether to aggressively treat the remaining fish, (although most fish in the tank are probably and appear to be infected, or to let the disease run its course, and to treat after the fact, and start the tank fresh.

Hello; Sorry to read of the outbreak. Thanks for posting this real experience.

You're not alone. I recently bypassed a QT and ended up with a tank full of gill fluke infested fish. Very stupid.

Prazipro quickly cleared things up, but not before losing numerous Barbs and a Loach.

Dosing Praziquantel certainly won't hurt anything, but if things look to be too far gone. Maybe save the medication for another rainy day.

A friend that ran an aquatic exhibit at a municipal zoo quarantined all fish for a minimum of 6 months, before allowoing them into a display tank.

I pulled out 3 more dead ones this morning.
Should have followed his lead.

None of the newest fish (Astyanax tetras) have yet to bite the dust, I have the feeling they are simply disease carriers, that are (as of yet),
that have immunity to what ever they are infeted with.

So sorry to hear.
I think that most of us agree that 6 weeks is a pretty good time for quarantine. Shocking how resilient the new fish were and how susceptible the old ones are. I'm not sure if a longer quarantine time would've changed the outcome. Sounds like they were resistant "healthy" carriers of a deadly disease.

Maybe there is some resistance your new entries have as carriers?

Sorry to hear about the bum luck. Wonder if it's that dreaded 'tetra disease'? Seems odd it would strike that fast.
