Ah! My specialty! Aquatics! Finally someone makes an aquatic topic. :P Anywho....
Ived kept alot of fish in my time and I still do. I have succesfully mixed and matched certain species of animals you wouldnt think its possible and have succesfully kept them.
When you are trying to mix animals you want to make sure you get both animals environment correct. Dwarf frogs like shallow water(1foot is a max) with plenty of plants. My suggestion is you either get fake plants or live plants. Make sure its leafy; this will allow the frogs to hang on the plants and rest. Just like a beta fish. I personally know you can keep them with a betta fish. You can keep them with SOME gouramis. You can keep them with tetras. But remember you are adding a group of 5 frogs in a 14gallon tank. Which means if filled up and you put ornaments in there what you really have is 5-10gallons of water. Which gives you a limited amount. Opt for a bigger tank and you have more choices. IF you only keep like 2-3 frogs you could keep a group of SMALL tetras. Remember one inch per scale of fish per gallon is a general rule. Also depends on the filter that you have. If you go for a larger tank like a 20long or a 30breeder you can have more fish. In a 20 long you could have 6 tetras and 5frogs. In a 30breeder you could have either:
6 tetras(Remember when k eeping tetras it should be NO less than 6 per group), 5 frogs and 2 SMALL gouramis(aka dwarfs)

Or you could keep 3 frogs 13tetras.
You get the picture? You COULD keep shrimp with them as long as they are ghost shrimps since if they get eaten you dont lose alot. Also they only live 2-4years at most(shrimp). African dwarf frogs can live anywhere from 5-10years. This is just an example of the fish you could keep. Remember:
1)Look at the frogs water parameters preferance and t he fish prefarance
2)Try to give space enough to not cause probs.
3)Make sure they are the same size or a little bigger.

Stay away from:
1)Large aggressive fish(cichlids, larger tetras aka piranhas, oddball fish, puffers)
2)Messy fish(goldfish, plecos, etc)


Hope this helps.
Personally when I had clawed frogs I kept them with larger gouramis, large corydoras, and faster fish. Gouramis are too big to swallow and corydoras are also too big. Anything too fast will bore them eventually. This is an example of what I did. Though you are keeping dwarfs so just keep smaller fish.
