Could somebody please tell me the actual name for the yellow fuzzy and tell me the proper placement? I just bought one yesterday and put it mid level(same level as a supposedly blue tort that is mostly purple and green and is doing well). It had really good PE yesterday and this morning(I'm at work so have no idea what it looks like now and can't post photos) so I'm thinking that it's OK for now. It's under leds and was under t5's at the store. My nitrates are steady at 0 for the last few months if anyone aks.
