Yeah I'm not getting the ones at my LFS they only carry males anyhow and IMO you shouldn't house two males together. They fight. They are sensitive this is true. From what I've read (and correct me gently if I'm wrong), After Initial fill up you really shouldn't have to do major water changes as the plants will eat up the ammonia, nitrite, and Nitrate so really only top ups are necessary? This seems odd to me but makes sense to a degree. I heard you're not supposed to remove Mulm... whatever that is. I also didn't add a timer... I'm going to need one with my schedule. Five hundred dollars seems like a lot... so I'll really have to save up. I'll save up 50 dollars a week and try to buy everything at once and hope its all still there. If not these things will come back.
