ok...your tank comes out to 5 US gallons which is perfect for a pair (2) African DWARF frogs.
sand substrate and a few live or SILK (not plastic!) plants - very easy to set up.
a low current filter
and a lid with no escape areas.
not too hard, right?
For a diet, I recommend HBH frog and tadpole bites if in the USA, or ZooMed frog bites if in the UK. Never feed fish flakes, they are not designed for their nutritional needs (you wouldn't feed your cat or dog, birdseed would you?). Frozen bloodworms (thawed prior to feeding) are a favorite treat and eaten with gusto!
A heater should be used to keep the water a stable 24-26*C or 75-78*F.
they are sensitive to water conditions of a cycling tank, so frequent water changes for the first few months are a necessity (2-3 times a week change 50% of the water and replace with conditioned water). After the first few months your filter will have cycled and you can reduce the water change to about 20% weekly.
It is important to make sure you are buying african DWARF frogs (ADF) and not african CLAWED frogs (ACF).
*ADF grow up to 1.5-2". ACF grow up to 6" and need massive tanks (10 gallons for one frog)
*ADF have webbing between the toes on both the front and back feet, ACF only have webbing between the toes on their back feet and four fingers on their front hands with no webbing.
*ADF are currently only available in natural color morphs (brown/gray with spotting). ACF come in a variety of color morphs - marbled (gray/brown with spotting), leucistic, albino, reticulated albino, and piebald.
* ADF have eyes that are flush against the sides of their faces, ACF have eyes that are perched on top of their heads.
these are just a few differences, the easiest way to tell them apart for newbies is the hands - webbing in front and back = ADF.
Pet stores will mislabel these frogs all the time, often simply calling them "African Frogs" or "Aquatic Frogs" so it is up to you to be responsible and know ahead of time how to identify the species.
ADF, Hymenochirus, are not officially called "Congos" or "Spotted Congos" - these are more fake names made up by stores to reduce their responsibility of properly informing you.
As I said, only me personal opinion from my experience of keeping them..
