a coby is a bottom feeder. it just swims around the bottom of your tank eatting the sand and spiiting it out. really to me it just cleans the sand all day.cool little fish to bad my puffer had mine for lunch last week now i need another.
I bought my LR in NOV. And it's just starting to show sign's of life. And as Plato said that dosen't mean your's will have anything.sorry but I wish you luck
