I purchased an australian whites tree frog yesterday and it at first was very green. But a while after putting it in the tank it turned a dark purple. it moved to the ground and threw something up (a wood chip?). I was worried but decided to wait a day. Today it was green again and slept all day, then an hour ago I gave it three cricket for dinner. It’s now turned purple again and is sitting (asleep?) in the water dish. The tank is clean, humidity is fine as well as temp. Does anyone know what may be bugging it? Im very worried and will take it to the vet if need be.
