Hello! I have recently stocked my 29 gallon planted tank (properly cycled, with lots of caves and hiding places) with 6 fancy guppies and 8 cardinal tetras. I am also planning to put in a dwarf gourami after everything is stocked. But now, I wish to know what I can use as a cleanup crew! I was originally going to put a couple peppered cories in there but I would like to know what my other options are. Shrimp? Plecos? (I really like them but I dont think they will fit) Thank you in advance for all of your answers!!!!!
