Hi everyone. I have a fairly new tank that I started up about a month ago. I had some trouble at first with some red eye tetras I got from Walmart. Im still not sure if it was my tank or the fish, because my zebra Danios did fine. Right now I have three black phantom tetras, a pepper cory cat (I think), five zebra Danios, and an otocinclus. Everything has been going perfectly for the past 2 weeks or so (my waters a little hard, but that's because of the tap water), and i'm looking to get some new fish. I think i'm going to give my zebra Danios to my dad because they were kind of just cheap starter fish, and I don't particularly love how they look. So now that my tank seems established, I am thinking that I want to get maybe another Cory, a few more black phantoms, some other schooling fish such as neon tetras, and 1 or 2 "centerpiece fish" (red tailed shark, gouramis, rams, apistogrammas, etc.). Any ideas?
