Hello,
for ADCFs (Hymenochirus) a daily temperature of 24°C should be maximum, 20 or 22°C is the minimum (e.g. at night). Higher temperatures are possible only for some hours per day e.g. in the summer.
pH level should not be higher than 7.0, 7.5 is the absolutley maximum, less then 7.0 always is better. Use Catappa leaves to make the water a little bit acid. Also the acid water will keep the frogs skin healthy.
Don't feed living red mosquito larvaes! This will work for several months. But one day your frogs will die immediately. Frozen red mosquitos larvaes not more than once per month or maximum once per week. Feed other frozen (and living) food together rarely with pellets. But don't use pellets with to small particles. These pellets only will polute the water, but the frogs are not able to eat them.

IMO 5 gallon is the minimum size for an ADCF tank. But in my experience here you can keep about 4 ADCFs easily.
Don't use a fast water current filter. Use a simple air filter like the billi filter: Billifilter . I prefer mat filters: Hamburger Mattenfilter . In tanks with this filtration you don't need weekly water changes of 25%. Commonly it is always good to change small amounts of water very frequently. Very frequently done large water changes for the frogs will cause problems with skinning.

In tanks with more than 15 gallons you can keep ADCFs together e.g. with small Aphyosemion species like Aphyosemion primigenium . But you shouldn't do it if you want to breed the frogs

Put in a lot of plants. The frogs like to relaxe and to hang around near to the water surface. Don't fill the tank completely with water. Just let 5 or 10 cm free for the air the frogs need for breathing. So the air will not to be to hot.
Long and strong ligthening only is important for light loving plants. I have 3 Watt engery saving lamps on my tanks planted with Anubias and Java moss.
