i just finished setting up my 15 gal tank today. andy0300 helped me with it a little bit. i decided not to use the styrofoam, andy sold me some baked clay pellets, and those ended up working well. i am going to house auratus in it. the only thing i need for it is some leaf litter for the areas that i don't have moss. let me know what you all think, and feel free to give any suggestions.
