Ive recently set up a new tank for the pac dude...it was fairly cheap and it looks nice..but will need an upgrade in the future....
5 gallon plastic terrarium..( exo-terra faunarium ).. $11.99
1 brick of eco earth..$5.99 / $11.99 for three pack
1 repti-therm mini heating pad.(small size for plastic terrariums(1-5 gal).$19.99
1 repti-rock water dish (small -$3.99 large-6.99
1 terrarium thermometer..$6.99
1 terrarium hygrometer....$6.99
(I also added a small light fixture made by Marina that was originally made to fit in small aquarium hoods which works perfectly for light when hooked up to a dimmer..it fits nicely over the feeding door and wont melt the plastic (optional) ..$12.99)
This setup may or may not meet the requirements of your frog...it can live in the 5 gallon for years but not for life expecially if it is a female frog (they grow bigger) I personally didnt want the ten gallon right away due to lack of space..also note that you may need to cover some of the air holes in the plastic hood.which is easily done with some saran wrap.
please note that all of the prices i have stated are in canadian funds..and may vary depending on where it is you live. it is a fairly nice setup for under 50 bucks (without the light)
also take into consideration that you may not need a heating pad..depending on where you live...I live in ontario..which is rather cold this time of year..so i need the heater.
you should buy a spray bottle to keep the soil moist and humid..mist a few times a day or whenever the soil looks a bit dry..try to keep the humidity above 60% at all times (by partially covering the air holes in the hood.)
hope this helps..pm me for any further questions
