I've had 2 'events' in my career.....
One about 6-7 years ago, in a 'bank' of vivs [about 16] that were all situated together on one wall, the entire collection of pumilio purchased from a well know FLA breeder died. There was some influx into the 20 + pumilio collection though, from some matched animals from the same source that I added from a NY hobbyist to create proper pairings. Anyway, they all perished and I had to resort to pulling all the vivs apart and bleaching them outside. PITA. Ultimately they stood dry for a year b/f I reclaimed them.
the second event about 2 years ago. I had been housing 3 of the most beautiful canary yellow Rio Guaramo WC/FR females I had [and still have] ever seen, for over a year....waiting for the 'perfect' male to come around. Well, a friend in FLA sent me a WC/FR new imported male from SR [he had housed it in QT at his store/shop in FLA for some weeks and 'treated' for typical intestinal and bacterial pathogens prophylacticly. Well within a week of his arrival I had eggs everywhere, then the frogs died, all 4 within days. !
Again, another tank that got the 'bomb' treatment... ;-(
Now, lets talk Ranavirus more. Who tests for it? what do we know about prevalence in the hobby? is it fatal? visible? PCR testing only? any treatment? Are we at all worried??
In both my cases frogs were from FLA/Panama imports, I jumped the gun and added them to established groups/tanks, and I lost them all quickly necessitating drastic sterilization measures.
And here we are again, with a multitude of pumilio imports coming into FLA and a big 'buzz' about them in the hobby. So much so that Ive been told 1300 frogs have moved into collections across the USA in the past 2 imports from Panama alone.
