Help!!! Three frogs have died ;-(

[Arabella]

okay I have taken photos of the other guys. Two of them have dark brown throats and the largest one has a lesion on his leg. All are not eating well and are not looking healthy. Please tell me what to do for them. I called the closest vet and they said the best they can do for me is do an autopsy on the one that died to find out what killed him.
this is the young one that has a dark throat:

The large one that has a sore on his leg

Im sorry your frogs are sick. unfortunately when ever you introduce new frogs to your existing frogs there is a risk and a isolation period it always recommend. You need to get them to the Vet asap. Good luck Arabella.

Was your Gray frog living with your Whites frogs?

I hope you find an answer soon Arabella... sorry about your other frogs. That's terrible all the vet will do is an autopsy, don't they carry any antibiotics? My tree frog has been on meds for the past four days and he's slowly getting better. Will keep my fingers crossed for you.

First never mix species. Its a disaster just waiting to happen. Amphibians have porous skin and use toxins to protect themselves from predation. So keeping different species together means they will be absorbing each other's toxins, for which they have no immunity towards.

Second, as Ebony has pointed out, all new animals need to be kept seperated from your established animals. Not all diseases are readily noticable. So a quarnatine period of 30 days is needed.

I would definitely take the surviving frogs to a vet. Where abouts are you? Maybe someone knows a good vet in your area.

just an update: Everyone is doing better since being quarantined. They are getting their green color back and are moving around more. :-)
