Hello everyone. I have an adult (4") Xenopus laevis and I am wondering what species of South African fish would be compatible with her. I am trying to setup a South African wetlands biotope. I currently have her in a 20 gallon long aquarium. I don't plan on putting any other creatures, (aside from my other frogs once they become a bit larger), in there with her until I get a larger tank. I'm just looking for some insight as to what may be compatible with her in a wetland biome.
