Had the conversation in my head??

Probably

I'm not really sure what you mean by like ping pong balls. I don't know how I'd describe the sound. It will be easier for me to just upload a video tomorrow.

I think it's pretty much the same as X. laevis from what I've heard on youtube.

One of the distinguishing physical characteristics of X. borealis is a prominent tentacle just below the eye (a subocular tentacle), which appears to be absent from the frogs in the photographs so I think you can discount them from being X. borealis. Also, X. borealis's call is a loud clicking noise resembling a pebble being tapped hard against the aquarium glass. Although it's true that the markings and coloration of the frogs in the photos are similar to X. borealis and X. amieti, they appear to be the wrong shape for those species, which tend to be plumper. If I were pushed to guess, and it is only a guess, I'd say that the frogs were just a variant form of X. laevis. Their diminutive size might just be the result of successive captive-bred generations. The only reliable way of finding out what they are is by trying to trace the source of the original frogs through the person or people from whom they were acquired.





The "chameleon" colour change in the frogs that Gemma raised in an earlier thread, http://www.frogforum.net/aquatic-cla...leon-acfs.html and mentioned again here, isn't that uncommon in other species of frogs and toads. Here in the UK our own common frog (Rana temporaria) can be brown, green, yellowish and various shades in between depending on its surroundings. I've also observed the skin of our common toad (Bufo bufo) change from dark to light when its surroundings have changed likewise. It's all to do with melanin and hormones.
