Each frog you have needs between 7 to 10 gallons of water. One frog is fine in a ten gallon tank but two frogs is not. You need 20 gallons min for two frogs. Overcrowding can lead to the death of your frog. They can become stressed out which will weaken and wear on the immune system; which in return makes your frog more susceptible to disease.
Substrate
There is no wrong to set up your tank. Some of the popular setups for substrates for the tank are bare bottom, river rocks or gravel. If you are going to set up a tank up to have a bare bottom I recommend investing in a baster. A baster is good to suck up left over food and debris. If you are using river rocks make sure to clean the bottom of the tank often because this type of substrate will trap waste and debris and cause the ammonia level in the tank to rise. Gravel is the last option. I have one tank that is set up with gravel and have not had a problem. The gravel I picked is on the larger size. I dont recommend gravel that is small in size, your frog may accidently injest it when feeding. Injested gravel can be harmful to the health of your frog. It can get lodged in his or her mouth and it can block off there airway. I have 2 tanks, a 36 gallon and a 20 gallon. The 36 gallon tank has gravel as the substrate and it has my biggest frogs in there. The 20 gallon is a bare bottom tank and contains my froglets, I did not those frogs to injest gravel because they are use to sinking pellets.
Filtration
Filtration is key! These frogs produce a large amount of waste. A good filtration system will help to remove the waste and provide "good" bacteria which will keep ammonia levels in check. It is important to let your tank cycle, it is normal for the tank to be a little cloudy when you first set up the tank. The nitrogen cycle has not happened yet but once the tank is allowed to cycle the tank will clear up. I also use StressZyme in my tank. It will speed up the rate at which a new tank will cycle and will break down organic compounds that can cause dangerous conditions in your tank, i.e. ammonia and nitrite. Also please make sure that the back of the tank is taped up by the filter, these frogs are escape artist. I recomment using a gutter gaurd and cutting it to size around the filters and holding it down with duct tape. I have had 2 escapes and was lucky both times that my frogs are still around.
Water Tempature
The great thing about these frogs is that they do not need a heater in the tank. It will not hurt if there is a heater in the tank. I have one in my 36 gallon that is meant for a ten gallon tank. I only use the heater in the winter because the tank is near a window and I dont want the frogs to get cold. The 20 gallon tank has no heater. I set my heater for about 70F. These frogs do well in tempatures that range from 65F to 75F.
pH
The pH in the tank should be between 6.5 and 7.5. They are hardy and do not seem to be affected by pH. I also do not mess with my pH unless it gets on the low side. I recommend Seachem's pH 7.0 Neutral Regulator. It will adjust high or low pH to 7.0 in the process it also removes chlorine, chloramine and ammonia.
Decorations
Frogs love places to hide and decorations will help to make your tank more attractive and lively. Make sure that your decorations do not contain metal. Metals are harmful to the health of your frogs. Also make sure none of the decorations have rough edges that can hurt the frog. I use live plants (anubias), and fake rocks found at the local pet stores.
