@CoryThank you for the fast reply and the help. funny story. I told my girlfriend I started listening to this aquarium co-op podcast and I played some for her. shes like that's great, so your really starting to get into this hobby? I say yeah, the only other guy I can find I like is this guy on youtube. I play her a clip of that guy and she says, babe, that's the same guy. look it says aquarium co op. lol. anyway, should I get a spray bar? Also, If I do just blue and yellows with 2 redtails. How many blue and how many yellow? I listened to your podcast where you explained it like a family in a crowded hotel so I understand why overcrowding works. im just still not sure on the numbers. Also should I put the red tails in first, then a few weeks later the yellows, then the blues a few more weeks later?
