Red Rummynose's seem to stay altogether at the bottom of the tank. They pick an area and stay real close to it. I have 8 and they are always together. At times they will bunch up with the Blood Fin Tetras.

Blood Fin Tetras are another schooler. I believe their the most active fish in my tank. At times they form a ball and circle each other and will circle other Blood Fins to encourage the school. I have approximately 17 of these guys.

Cardinals are also a good schooler. I think their is 10 in their now. So if you add up the rummynose's and the Blood Fins and the cardinals together they form a awesome display when they all school together.

Neon Tetras are another good schooler. I have difficulty keeping them in my tank. Most of the stores have them but they are less than a half inch in size. They tend to turn into bait for some reason. I started out with 20 and now have 3 that are over an inch. I've learned to buy fish at least over an inch so they don't become a snack.
