Well I am back from the fish store and I have 4 new occupants in my tank. I had 1 Black Skirt Tetra so I knew I needed more so add 2. Also picked up 2 Black Neon Tetras for a total of 4 new. There was 2 fish in the tank already so I added 4. If all goes well this week and levels do not get wacky on me, I will add 3 more of each to fulfill the schooling needs of the species. Now I am looking at building a bigger tank.
