So I was thinking of getting a dwarf puffer but can only find very basic info on them, such as fresh water (not brackish) and snails for food. Does anyone know of a good place with lots of puffer info (pH, water hardness etc...). Also I understand that they get to be about 2.5" long. Would it be okay to put a single one in a well planted 5 gallon tank (I just don't have the space for anything else right now and don't plan to anytime soon). and 1 more thing, if I can keep one in a small tank would it be okay to have a couple cories in there or should he just be left alone. Thanks
