yeah, they make pretty cool pets. heres some of the basics:
15 gallon for one, 20 gallon for two
plants- birdsnest ferns can survive the constant jumping
they are nocturnal, they usually sleep in a plant or in the corner of the tank during the day. at night they eat and get increadbly active, they are great eaters and it's really fun to watch them.
temp- above 70, u should get a basking bulb, the blue ones don't burn the plants and still supply a lot of heat.
wood- they need this because they are so heavy to perch on. it's thier "lookout" tower when they are hunting for food.
water- mist daily and they will be very happy frogs, the males usually croak, sometimes they will just hear the toilet flush or the car start and they start croaking. keep a large water dish in the tank, but not so they can't keep their head above water. top- glass tops keep humidity in, but if you get a basking lamp u will need a screen top.
food- they eat pretty much any bug, i feed mine crix, they can also eat pretty much any kind of worm- earth, meal...
gender- females get bigger, males croak, it's really fun to see and hear they croak. i have two males and when one of them starts the other joins in and they go back and forth. if you get two males though you will need at least a 30 gallon cuase they are territorial. don't keep more than one male with a female, because they will fight over the female. as far as personalities, i don't know because i've never had a female. they are sexable after about 6 months and the males will start to croak around that time. good luck!
