ha funny that you mention the plants!, they constantly tear them up! once i spent about 50.00 on live plants and they had them turned into a nice salad by morning the very next day. ive had the red the longest but they really dont fight or bully one another, so its hard to say who the tank boss is, but if i had to pick i would say the tiger is more aggressive. i believe my red to be blind in one eye. never saw any damage to the eye, but i can drop their food in on his left side and he totally doesnt know its in there till he spots it with his right eye..
