Bloat is one of those ailments that can be tricky all the way around. Being it is a symptom of a couple of different causes, it can be tough to treat. personally I feel that WC vs. CB is not really a factor. Just recently I was shown pictures of a wild
Ambystoma sp. with a horrifying case of bloat!
I would not panic about this specimen just yet though. (OK...
I would, but ask around here and you will find I panic about just about everything involving my pets...
)
In this case, I would separate the animal and keep her in bottled spring water with a chunk of limestone large enough she cannot eat it. (I suggest this as it is the simplest way to get her in good hard water in my opinion.) I would offer her small amounts of food such as chopped nightcrawler, or any of the frozen foods we discussed earlier. You will definitely need to cool her down. I also suggest checking around with the vets in your area and see if any of them have experience treating amphibians, just in case she does not improve.
Looking at your water chemistry, I do not think water changes are going to do anything but create problems from the stress to the animals.
I
am a bit confused about your gH and kH results- Did you convert the results to PPM? If so that water is far too soft for most caudates,
Neurergus kaiseri especially. If not, you may want to retest as those results seem a bit too high for the gH and kH scales I am familiar with.
