Since being on this site i've noticed quite a few use sand as substrate and i really like the look, is there a specific kind to get? will some fish not handle it well? I have one tank with GSP and its set up brackish, and then another with Platys and a pleco... Is there white sand? lol i'm sorry if that's a dumb question, i'm very new to fish keeping but it's become such a passion to get bigger tanks because they are just beautiful. Thanks in advance
