well, now I'm White's Tree Frog less

Rimmer stopped eating a few days ago and passed away during the night. I've called my vet about doing a necropsy to find out what the issue was, but they said they'd have to send it out as it's specialist in nature and would cost me about £200 (which is about $320 USD), which I sadly don't have kicking around. I've contacted a specialist vet, and after telling him the symptoms and letting him know at least 2 other people have had the exact same issue, he thought it sounded like an Aeromonas or Psuedomonas bacterial infection. When I looked that up last night, I found this information:

"Red leg" (Aeromonas hydrophilla)

Aeromonas can devastate captive collections as it has both contact and airbourne transmission, but it does occasionally cause outbreaks in the wild, as it did in the UK after they already had an outbreak of ranavirus. The common name of "Red leg" is given because the disease will cause a pinky-red flush on the underside of the thighs which can also spread to the belly area above the vent. Any bacterial problem in amphibians can cause a pinky flush in this area so this symptom alone is not enough to indicate Aeromonas. There are other symptoms as well which demonstrate the pathogen's attack on the skin such as a slimy pasting occuring all over the body or mostly underneath (the ventral surface) and ulcers in the skin which will be concentrated on the feet, legs and sides of the body. The frog may lose weight quickly, become lethargic, and it might also become paler than usual. You will need the antibiotic Baytril (enrofloxacin) from a vet

Pseudomonas

This disease is unfortunately a treatment resistant problem. It is an aggressive tissue-eater and extremely painful. It is fast and can kill a frog in only a couple days once clinical signs appear. The frog will become very bloated, become lethargic, change to a dark body colouration and for the Common Green (White's) tree frog (Litoria caerulea), pale mint green spots might appear. Very few antibiotics will work against Pseudomonas - Gentamycin is one and ciprofloxacin is another. There is no time to waste if Pseudomonas should appear so we would suggest that if you keep frogs - especially the Common Green/White's - that you have gentamycin on hand in your refridgerator at all times. Both gentamycin and 'cipro' are nasty antibiotics so extended use of these is not recommended. With painful conditions such as this, painkillers can be used on amphibians to relieve suffering and reduce stress so that the antibiotic MIGHT have a chance to succeed.
I've contacted the seller again, this time by phone, and relayed the information I was given and he says this is something that naturally occurs in water. However, I only use bottled water for all my animals (or dechlorinated for the water monitors). So if that's something that naturally occurs, then dang... I've got this as well.

Does anybody have any experience with either of these bacteria in their collection? Without actually getting a post mortem done, I know it's going to be hard to pinpoint what exactly went wrong, but if anybody can give me some information it'll be helpful.

The breeder has offered me a replacement or a refund by the way. I think I'll take the refund.
