I have a African dwarf frog, (I know they are social animals, I am going to get more)he lives in a fifty litre tank, and I want to stock it. currently, there is him and 3 otocinclus in there, and I want to add a pair of honey gouramis, some platys and some small schooling fish. I don't know I should stock a full community, or leave a lot of space so he doesn't get stressed with a lot of fish around him. what are your thoughts on this, and what do you think I should do ?
