so if i do get rasboras, they just prefer live plants right? they dont have to have them to survive, im not sure as to how to take care of a planted tank. so im just thinking about cutting down the chances of me doing something seriously wrong and killing off my whole tank. also can i pick up anything on a walk and use it? i know i have to boil and scrub it but what else must be done to make sure its safe for use?
