The truth is the place where i stay has very little option for an aquarium hobbyist..the LFS here don't have that many kinds of fishes..and almost literally they never have any aquatic plant...so for plants you have to go to a lake or a pond or sometimes even rivers..lol..and let alone any kind of algae eaters..SAE,otos,shrimps,brittlenose pleco..nothing..i'm havin an algae prob and i'm kinda desperate for an algae eater and that's when the sharks came into my mind..and btw no pressurized CO2 available here..goin DIY..
