I don't know how many people are interested in these but I used to keep them in several planted tanks, they breed easily on their own and young ones are eaten by most fish, they only get a little more than three quarters of an inch long so most cichlids will eat adults as well, they eat detritus and fish food. They have not been easy to find at a decent price so I thought I would share this link, http://crayfishshop.com/product_info.php?products_id=103&osCsid=d68447d9f8f7936547925eb6c3d0c9f3.
If you have a little 2 to 5g tank laying around or full of guppies you might add some elodea and get 20-30 0f these and toss them in there. They love green and blue green algae and are quite hardy. here is a pic, forgot what site it is from, one about fly fishing.
