It’s a commonly held belief that you cannot mix angelfish with Tridacnid clams. While this notion is very true for a wide variety of different species, especially those in the dwarf angel crowd who are fond of clam mantles, it isn’t the same for all. Many fish, like the Bellus angel for example, play nice in an aquarium full of clams, as they are not known nippers. Instead, they are planktonic feeders who get small particles of food directly from the water column. If you are a clam fanatic (such as I am), but also want to experiment with angelfish, start hunting for the experiences of other angelfish owners or try placing the two animals into an experimental setup of your own. If you decide on testing the waters for yourself, just make sure the clams are positioned in such a way that they can be easily removed from the tank if the angel decides to develop a taste for them.
