my sandbed has a bunch of waste from my fish. i have a 25 gallon tank and only one small crab and one medium sized snail. should i get a shrimp, or more crabs, or what? I know that I just need to put the right species in there and it will be cleaned up right away. Just not sure what is best for the sandbed. i stir it up about once a day maybe more, but it doesn't seem to be sufficient.
