If you are looking to breed frogs,you will most likely need to construct a Rain chamber.

Rain Chamber
What is a Rain Chamber ?
A rain chamber is container in which you can artificially simulate the rainy season to stimulate frog breeding behavior.Its a very simple and straight forward procedure.
All you need is the following
- Small aquarium or plastic tub Aquarium Tank, Glass, 20 Gal
- Clear flexible tube with some joints Aquarium Clear White Silicon Tube
- Aquarium pump Rio Plus 1400 Aqua Pump – 420 GPH
- Duck tape
- 2 hinges
- Suction cups 20pcs Aquarium Suction Cup
- Extra glass panels (according to your project)
- Acrylic panel
- Aquarium silicon Aquarium Silicone 10.3 oz, (304)ml
- Some live humidity loving plants (here i used pothos) Golden Devil’s Ivy – Pothos – 6″ Hanging Pot
- Aquarium heater Aqueon Pro Heaters Submersible,200-Watt
- A timer Lamp and Appliance Timer with 2 On/Off Settings
Cover the sites of the aquariums with tape to cover areas where you dont want silicon to stick
Cover the sides of the glass panels and at some point add the 2 hinges
Attach acrylic panel on top after you drill some holes for ventilation
Apply silicone and press to clue firmly.You might need to use more silicone and spread it evenly from the inside to cover any gaps
Make loops with the flexible tube and position it on the top of the aquarium using suction cups,then make some holes randomly on the tube and try to spread the rain droplets evenly across the chamber

Use suction cups to attach the live plants
Install the aquarium pump and connect to the tube.Make sure to block the other open end of the tube,either bend it or use a plug
Fill with water and start testing the rain,you may need to add some more holes on the tube to spread the rain evenly
After you get the result you want its time to add the water heater and set it up to the appropriate temperatures for the frogs you are breeding. Add a timer and set the timer and connect the aquarium pump to go on and off at specific intervals (i used 30 minutes on and 15 minutes off)
Add the frogs and good luck!
