This is a video of a 75-gallon river tank that I set up in August, 2010, to house a group of Herichthys tamasopoensis and Xiphophorus montezumae. The video was shot two months after setting up the tank and shortly after getting the swords. I am posting it today because I just filmed about 10 minutes of great footage of the same tank. I have made some changes to the filtration and water flow, and the fish have grown considerably. This video is for comparison to the one I will upload soon.
