OK.. You say they were just shipped in on Thurs.. I assume your talking about imported.. so, that said, Brace yourself for a tough few weeks. Way less than half of imported frogs make it. There is a huge stress in shipping, few people give them any medical attention when they get to the states, and generally, the weaker frogs are easier to capture, so that is what gets sent.
NOW, I am not saying your animals won't make it, but I am saying you will have to learn alot about RETF's in a very very short time and provide proper care for the animals.
I would strongly suggest that you find a good caresheet and memorize it (the one I usually recommend can be found on www.amphibiancare.com under caresheets.
I would also contact Dr Frye (or if you have a local herp vet that can do it) and have fecal tests run on the frogs. It is relatively inexpensive, and an excellent way to find out if you have parisites or other cooties.. and they can help you treat the problems. Dr Frye can be contacted through his site at http://www.fryebrothersfrogs.com/, click on the DR Frye icon. I think he has a price list on there as well that will let you know what a fecal test will cost.
Ok.. so to your specific questions, just becuase it is hanging upside down doesn't really mean there is a problem. I find mine hanging upsidedown on leaves all the time sleeping. I will also tell you switching to a tiny tank will cause stress. You will need to pay a lot of attention to the heat and humidity in there as it can dry out very very quick, and get to hot very very quick, either of these will certainly not have a good outcome for your pet. I know it is spending more money.. but I would go get a 10 gallon tank and a glass top if I had a frog that needed to be seperated.
Now, if he was on the ground on his back.. you have to get in touch with a vet ASAP.
As for the protrusion.. I have no idea.. if you can get me a pic we may be able to figure it out.
Make sure you get them plenty of fresh water, good food sources (dust them with calcium and vitamins every couple of feedings) WC will certainly need the extra boost that vitamins can provide.
Now.. the top two mistakes made with RETF's are errors in husbandry (meaning wrong type of enclosure, wrong temps or wrong humidity) and to much stress. The first is pretty self explainatory.. the later though, is usually caused from to much "help" from well intentioned keepers. Everytime you open the cage, move one to another tank.. nudge them to wake em up etc.. you take a chance on stressing them. This guys are very very proned to stress.. and it will not have pretty results.
I don't mean for the post to be negative.. but make sure you doing the best you can, as with WC animals.. it is very tough for the first several months.
That said.. and a message to everyone reading.. I know they are cheaper, and usually easier to find.. but if you want a tropical tree frog or a pdf, and you don't have years of experience.. make sure it is CB.. this will eleminate a lot of problems and help to ensure you have a frog for a nice long healthy life.
If you like, you can email me at bogart6868@aol.com and we can correspond with a quicker response.
Good luck with em..
