Isn't it neat to see SOOO many together? Really gives you an idea of WHAT schooling means. I am so spoiled. I bring in all these awesome fish, keep them in species tanks wiht hundreds of their friends, and really get to see HOW they behave. Its why when a lot of people ask me for advice, I may dissuade them from species in order to better see their behavior. I am a firm believer of MORE of each species rather then a few of several. For instance, once you have seen 800 habrosus cories together, you would NEVER consider less than 30 in a tank. Same goes for a lot of these smaller rasboras, danios, and tetras. Seeing them in huge groups just speaks volumes for their behavior. Its totally worth it to get big groups of a single fish as their behavior is just amazing.
