I enjoy watching my betta, over the other fishes or aquarium life that I have had. I have had a betta, a few differnt species of corys, some bamboo shrimp, red cherry shrimp, and bridgesii snails. My favorite has to be my betta or my red cherries. My betta is ERY interactive with me. Everytime I come up to the tank, he reacts differently. Like last night for example, I was playing with him. He'd come up to the tank, and he would put his mouth ABOVE water waiting for me to give him a treat. Then he would grab the worm, eat it and then swim in a circle while flairing, then he'd come back for more. My Red cherries are just interesting in general. I also was fascinated by my snails when I had them. VERY interesting creatures, especially when you have multiples geting to see them interact w/one another.
