| Re: 40 gallon freshwater reef There are a couple of FW clams that are suitable for aquariums, but they are boring and dull. There are also a few amphibians, most notably, the dwarf African clawed frogs. One tip, if you really want everything to thrive, choose species of plants and animals with similar pH requirements. There is alot more variation in pH and hardness needs for FW.
