Hello and welcome to FF ! Best thing to do for this baby is to set-up in a quarantine like enclosure, preferably, one with a vertical disposition. Use damp (dechlorinated tap water) unprinted paper towels for substrate and add a small water dish no deeper that frogs chin (a small plastic container top will do) and a silk type plant. Cover 3 sides with aquarium background and you are set to go. Change water daily and paper towels every couple days.

When frog has grown and is stronger (3-4 weeks) you can move to a regular substrate like shredded coco or coco mat according to your preference. Depending on species you will need to get a larger ExoTerra style enclosure. A Green will do fine in a 12x12x18; however a Grey will need much larger space.

Feed FF and pinheads as Eli recommended and dust them with supplements per this: http://www.frogforum.net/food-feeder...schedules.html. Crickets should be sized same as distance between the frog's eyes and gut loaded with carrots, lettuce, and cherios cereal for 24-48 hours prior to feeding frog. Hope this helps and good luck !
