As requested by the many fellow arowana enthusias in the forum. I have attached some pictures of my red and crossback arowana comm. size is 5 by 2 by 2 running on a 3 feet wet dry sump tank. Fishes are about 10 inches. The 5 reds are from Isaku Arowana farm and the gold head crossback is a VIP crossback. Please feel free to give me any comments. As for the question of overcrowding. This is a temporary holding area for them. I will be transferroing them to a bigger tank when they hit about 14 inches.
