green tree frogs

Question
Is it ok to house green tree frogs and house geckos together??  Also do you have any info on bloat condition in tree frogs?  We were given 3 green tree frogs and two geckos for my husbands classroom, we have had them for two months.  After bringing them to our house for the holidays one is suddenly sick....he bloats upand then deflates looking emaciated...we have seperated the frogs, one other frog looks like he is losing weight.  I have been researching all aspects of frog care over the past several days, if you have any suggestions we would appreciate it.  

Thanks
Wendy

Hi Wendy, House geckos and green tree frogs are compatible sizes and require similar environments. They are often housed together successfully in community tanks. There is always some element of risk when combining species, particulary ones likely wild caught (as those two species most likely are) from different  parts of the globe.
They will be exposed to each others faeces and the bacteria etc. that may be normal and harmless for one species may not be as harmless to another species. I prefer to create communtity tanks with species like green treefrogs and green anoles that share the same native range and occupy different niches in the tank. The frogs are active at night while the anoles are active during the day. This reduces the level of interaction between them and any resulting stress from that.

Bloat in frogs can be caused by both fluid or air and it can be a symptom of several conditions. Infection is a very common cause and that would be my suspicion in your case. It sounds like the frogs have gone through a couple major environment changes recently with the move to the class and then to your house (unavoidable moves, I realize). This, along with any handling of the frogs is a real stress producer for them. Stress really negatively affects their immune system as it does for us and makes them really vulnerable to infection.
Antibiotic treatment is an option but you will need a vet's input on that. In the meantime, you can boost their immune system function by increasing their heat. A small wattage lamp over one end of the enclosure that warms an area to around 85F would help. Keep them in a quiet area and avoid handling unless necessary. Keep the tank and water very clean and use an aquarium water conditioner to remove the chlorine and chloramines.
