Hello Lil,

sorry, my english is horrible, i hope, you can understand me.

I had in the last years 72 Litoria caerulea - Babies and adult one.

How old or big your whites?
The tank from you is too small. Please buy a bigger one.

Good, i have a tank with 130x40x140cm for my 9 Whites. But i think for 2 Whites (adults) you need minimal 40-60x50x80cm.
And for your babies (i think 2-4cm) minimal 30-50cm cube or bigger.

You don't need a heatmat for treefrogs. In Europe we make the heat only whith light.
It is not good and reality for treefrogs. When you buy one, you must test, how hot is in the tank.
The glas must be so cold, that the frogs can't burning her feeds on it.

Nice greetings from vienna,
Irina
