I'm trying to come up with a few future stocking ideas for when I get myself in a more permanent living situation. Initially one of my plans was to get a 15-20 gallon with African Dwarf Frogs, Corydoras, and Guppies. But I am concerned the guppies will out compete the frogs for food (I am a beginner aquarist, so the less trouble I get myself into the better), so I am thinking of putting them in separate tanks. That being said, I love multispecies tanks, but I also love the ideas of adfs, so are there any tankmates that are better suited for them? More general questions: Could I keep ADFs with Nerite snails? Or would they eat them? Would Corys compete with ADFs for food? Are there any small, hardy species (3 inches or under) that have diff food requirements that would work well with ADFs? I'm not setting up this tank anytime soon, but I want to have a good idea of what species I might get so I can do extensive research on their care and compatibility before I get them.
