Brandon,
Sorry to hear of all your loses. So sad.

Yes, definitely something recent went on to cause this. Infection, something getting into tank to poison, hard to say.

I would definately clean that viv out. Also, post a pic, someone might see something out of the ordinary.

A 20 gallon is pretty small for 4 Litoria caerulea since they do tend to get large. They also need height so setting up a viv with more height than floor space is recommended.

  • Has anything changed with the water source provided?.
  • Were all plants been rinsed and free of possible fertilizer? ( a slow killer when absorbed by the frogs)
  • When the first frog passed, was it separated from the others once you learned it was becoming ill?
