Peculiar spots I need some help with..

[LadyIvy]

So, I'm the proud owner of four Whites Tree Frogs. The live in an 80 cm x 50 cm x 50 cm habitat. A new one is on the way, this one is too small and just a secondary solution. The habitat is a paludarium which they share with some Microrasbora Galaxy Fishes. I have three males and one female, called Mechthilde. She's a beautiful blue phase with tiny small white freckles on her back.
I'm a very experienced terrarium keeper, so that's why I'm here asking for help because I've literally run out of possible causes for Mechthildes condition.
Mechthilde is not yet a year old but indeed very big and a bit chubby. She's fed grashoppers and crickets which I breed myself, also sometimes an earth worm.
I've bought her in Spring together with Waldemar, an olive green male.

As I gave them a tiny swimming lesson (Trust me, they love it) I noticed tiny red dots on Mechthildes hind-leg. The dots are a little elevated and don't seem to cause her any distress or pain. But to me it look like a chemical burn or rash of some sort, the kind you get when you touch poison ivy. However, where I live, vets do not care for amphibians or reptiles. It's also getting worse, it is spreading.
I've combed the internet for possible secondary cases but was left without any further examples of a similar condition.
She's always by far been the most lazy frog I've had, she doesn't even bathe too much. But she eats regularly and has a good digestive system.
Also, the other three frogs seem to be unaffected, they are just as active and hungry as always.

I think it's going to be hard to diagnose without some professional help (in the form of swab taking). Could be bacterial, fungal or even viral in addition to a possible reaction to a chemical or something. I'd definitely quarantine from the others until you know, surely swab testing can be done by vets in your area even if they don't treat reptiles and amphibians?

Hello Diver,

Thank you very much for your answer. Yes, I guess thats doable. She's in quarantine in a sterile environnement. I'll keep you updated.

She needs to be seen by someone... would there by any way you could contact a zoo vet if your companion animal vet won't do exotics/herps? I'm wondering if it might be a form of tapeworm that resides under the skin then will emerge from the blisters (can't think of the name of the condition right now). That will need experienced intervention and medication.

Hello there!

Yes, that's what I thought. Because just about two days ago, she pooped segments of a tape worm. I have now contacted a vet for smaller animals and he suggests panacur,which I think is a good idea as well.
Thank you very much for your help!

I was thinking parasites also. Good luck!

Thank you all for your responses! I appreciate them a lot.


So status update:

I treated all of them with panacur and now I'm hoping for the best. Her skin is looking awful still, but I'm positive it'll get better. I found out yesterday, that we have a tropical vet really near us since a few months, so in case anything goes worse, I'll just take her there.

Hope she's better soon! Good news about the exotic vet too. Good luck!
