I am trying to get rid of my red devil to make room for some fish I have coming in. He eats hikari pellets, krill, freeze dried shrimp, massivore, and algae wafers. I would like to see him go to a tank 30 gallons or larger. This is for pickup only, and he is about 7-8". Pix Below. Oh yeah, and he is extremely aggressive. He bangs the glass when you get close, and will quickly bite you if you put your hand in the tank. He will draw blood when he bites so you kinda don't wanna get bit. He also attacks the syphon when I change his water once a week.
