I want a prehistoric dragon goby, my tank is a 65g with angels, blackwidow tetras, and some cory cats. I do not not want to deal with the pain of getting it food so i am wondering if its possible to just buy some live organism, such as black worms, amphipods, and tubifex worms throw em in there so they establish a colony and call it good? its what i did for my madarin goby and it worked out fine but idk if the same works for freshwater. i figure the corys and tetras will help keep population under control. Sooooooo is it possible lol i know it sound strange but in the wild they live by eating small organism out of mud so why not. I have sand as my substrate btw.
